Do you have periods during pregnancy? Can menstruation occur in early pregnancy?

This is an important topic for a woman.

The question often arises: is pregnancy possible during menstruation? You may hear many stories about women you know for whom menstruation is the best method of contraception. On the contrary, gynecologists argue that menstruation does not protect against pregnancy, and sexual intercourse itself on menstrual periods is fraught with many infections.

Anatomy and physiology of the female body

Nature prepares a girl to be a mother even during intrauterine development. Many eggs are laid in the ovaries, and after puberty, every month one of them goes on a journey to meet the sperm. In case of fertilization, the fertilized egg descends along the fallopian tube to the uterus, where it is implanted, this moment is considered

If this does not happen, the egg is destroyed and the inner layer lining the uterus is separated. All this is excreted along with the blood, and menstruation begins. There may also be an option such as pregnancy during menstruation. The implantation was successful, but part of the endometrium still peels off, causing bleeding.

Possibility of conception during menstruation

Contrary to the popular belief that pregnancy during menstruation is impossible, there are many living examples that prove the opposite. The complexity of the female body and instability is also complemented by the vitality of sperm. They can remain active and fertile for up to 8 days; as you understand, during this time menstruation will have ended and a new egg may be released.

In modern life, stress, poor nutrition, various diseases and many other factors contribute to hormonal imbalance and cycle disruption, which means it is almost impossible to accurately calculate when ovulation occurs.

Safe days - can this method be trusted?

We often receive important information from unreliable sources. This is how girls tell each other that on their menstrual days (as well as the last ones before them) they are reliably protected from conception by nature itself. This is fundamentally wrong. Pregnancy the day before your period is just as possible as during it.

Only the first day, when menstrual flow is especially heavy, is relatively safe. But often a woman’s well-being is not conducive to sexual intercourse on this day.

It is safer to use suitable contraception at all times than to rely on chance.

Are menstruation and conception mutually exclusive?

Theoretically, these concepts are incompatible, but in practice, pregnancy during menstruation is possible, and spotting (in rare cases) can accompany a woman throughout the entire period of bearing a child. All cases can be divided into two categories:

  • The woman knows about her interesting situation, and suddenly bleeding begins.
  • The expectant mother does not suspect that she is not alone; menstruation occurs regularly, on time, without leading to such thoughts.

If the first case requires urgent medical intervention, then the second case is more complicated. They give rise to numerous questions from expectant mothers - do you have periods during pregnancy? This phenomenon occurs, but occurs infrequently, usually in the first trimester. Only an examination by your gynecologist will help eliminate any cause for concern, so do not neglect the consultation.

If a woman carefully observes her cycle, she will probably notice the difference between normal menstruation and menstruation. They differ in a number of ways: duration, abundance, color, smell.

Normal menstruation or spotting

From a physiological point of view, normal menstruation is incompatible with pregnancy. Because if there is a rejection of the inner lining of the uterus into which the embryo is implanted, then there is a threat to its life. Therefore, gynecologists call any discharge during pregnancy more correctly - bleeding.

Why does bleeding begin exactly on time, according to the usual cycle? It's all about hormones: somewhere the pituitary gland malfunctioned and, from old memory, starts the usual process. Because of this, some women cannot recognize pregnancy, their stomach hurts, how menstruation begins, all the sensations during PMS and pregnancy may also coincide (weakness, drowsiness, nausea, breast swelling), but a test or examination by a doctor will put everything in its place.

What do these periods mean?

Often, bleeding during pregnancy does not pose a threat to the life of the mother and child. But a woman needs to focus primarily on her own well-being. The absence of pain, vigor and good appetite mean that everything is fine with both of you, and a slight hormonal shift is not a problem at all.

However, be very careful, heavy bleeding, too dark or watery discharge, especially if they are accompanied by acute pain, is a reason to immediately call an ambulance. Such symptoms may indicate a threat of miscarriage, serious inflammatory processes, or an ectopic pregnancy.

Reasons for menstruation during this difficult period

Whether you have periods during pregnancy or not, this does not mean that your baby cannot be born full-term and healthy. What could be the reason?

  • The very first thing that can be assumed is an error in the calculations. That is, the last critical days are included in the period of pregnancy, although it came immediately after them.
  • - this is the moment of direct attachment of the embryo to the wall of the uterus. Usually only a few drops of blood are released, which are mistakenly taken as the beginning of menstruation.
  • The first period during pregnancy may occur due to the fact that the egg was fertilized at the very end of the cycle, and by the time it was implanted in the uterus, the process of menstruation had started automatically.
  • Quite rarely does a different scenario happen. Of the two mature eggs, only one was fertilized, however, according to the laws of physiology, they both return to the uterus, where one is implanted and the other is destroyed, causing menstrual bleeding.
  • Mechanical damage to the cervix during sexual intercourse.
  • Serious hormonal imbalance, decreased estrogen levels.

The pace of modern life, constant stress, and hormonal medications make any of these reasons possible. Therefore, only a gynecologist can find the only one, yours.

Menstruation in the first months after conception

Usually this problem concerns the first trimester, when the body has not had time to properly respond to pregnancy. Your period has begun, but the embryo continues to develop in the uterus, and by the next month the hormonal levels will level out, which will prevent the mistake from happening again.

Often there is a cycle failure, for example, menstruation began ahead of schedule. The pregnancy continues as usual, although the mother does not yet suspect it. If bleeding continues at a later date, the doctor should select a program to correct hormonal levels.

Do periods during pregnancy pose a threat to the fetus?

As noted earlier, bleeding during this period is not something out of the ordinary. Mom just needs to soberly assess the situation. Thus, discharge, comparable in strength and duration to menstruation, in almost 100% of cases means the loss of a child. The same can be said about bleeding with severe, cramping pain.

Scanty discharge, even appearing with enviable regularity, does not pose a threat to the life of the fetus, but is still the reason for a visit to the gynecologist. There are unique cases when menstruation continues throughout the entire period, and it all ends with the birth of a healthy child, but this is the exception rather than the rule. Why is this happening? The body, according to old memory, creates a hormonal background every month that is critical for bearing a child.

Menstruation during early pregnancy is a fairly common occurrence that does not harm either the mother or the child.

What to do if you are pregnant and your period has begun?

Assess the nature of the discharge and your well-being. If they are minor and you feel great, you can ask about the reasons during your next consultation. At the slightest change for the worse, call an ambulance; do not take unnecessary risks. It’s better to let the doctors assess your condition.

Sharp pain, bright scarlet copious discharge - all this indicates immediate hospitalization. Typically, hormonal medications, treatment of existing infections, and long-term maintenance therapy are prescribed.

Important date, last menstruation before pregnancy

The doctor will ask this question first when registering. Using this date, obstetricians calculate the due date of the baby's birth and the mother's maternity leave. If menstruation continues during pregnancy, it will be determined based on the results of the examination.

The gestational age of the last menstrual period is calculated from the first day of the last menstrual period. This is easy to do, just know this date and duration of pregnancy, namely 280 days or 40 weeks. Count 40 weeks from there and get the baby's date of birth.

What to do if pregnancy has already occurred, but your period continues? An ultrasound will help determine the due date, and with greater accuracy than calculating the last menstrual period. In addition, by waiting for the first movement, you can confirm the date of birth of the baby. You just need to add 20 weeks to this day.

Let's sum it up

A woman can become pregnant on any day of her cycle; the complexity of the reproductive system and its close connection with hormones do not allow us to reliably calculate safe days. In the early stages of pregnancy, it is not uncommon to experience bleeding that is different from normal menstruation, which can be considered normal. But if it appears in the later stages (more than 12 weeks), you need to consult a doctor.

If bleeding is comparable to menstrual bleeding, it cannot be considered acceptable during pregnancy - this is a myth. It puts the life of a woman and child at risk. Even the slightest bleeding requires competent study and search for its causes. Heavy and prolonged discharge (as during normal menstruation) indicates termination of pregnancy.

If, despite the development of your baby and good general health, regular bleeding (menstruation) continues, then your body categorically does not want to say goodbye to its hormonal regime. At the same time, you become one of the unique women, and here, no matter how much doctors say that this does not happen, the main criterion is how you feel.

Visit your gynecologist regularly, take the necessary tests and listen to yourself. A good mood and optimistic attitude will only benefit both you and your unborn child.

Pregnancy and menstruation are incompatible concepts. To understand this well, you need to study the basics of human anatomy.

The uterus has three layers - outer, middle and inner mucosa. The endometrium is the most mobile layer of the uterus, and as soon as a new life is born, it thickens so that it is not interrupted.

If pregnancy does not occur, the endometrium is detached and menstruation begins. This is why menstruation is impossible during pregnancy. Do periods in early pregnancy always warn of danger?

Causes of menstrual bleeding

Indeed, during early pregnancy, periods may indicate danger, but not always. Of course, if menstruation appears at the beginning of pregnancy, this is a kind of pathology, but it may not pose a threat.

Be sure to consult a doctor

Scanty periods during pregnancy do not pose a threat if...

  1. The fertilized egg does not yet have time to attach to the walls of the uterus before the onset of menstrual bleeding in the mucous layer. Then, it is likely that menstruation can occur in early pregnancy. This stage does not involve hormonal changes in the body, so menstruation can continue.
  2. Two eggs matured in different ovaries at once, one of which was fertilized. Then the second one is rejected and can cause menstruation in the early stages of pregnancy.
  3. Hormonal balance is disrupted. For example, a woman has a predominance of androgens - male hormones, or an insufficient level of progesterone. Both cases do not pose a threat to the unborn child. These problems can be easily corrected with the help of hormonal drugs; the main thing is to consult a specialist.

Pathologies that can cause menstruation at the beginning of pregnancy.

  1. Menstrual bleeding, which is observed at the beginning of pregnancy, may indicate detachment of the ovum, which leads to miscarriage.
    The body can solve this problem itself if the detachment is small. Then progesterone begins to be actively produced, and the discharge has a scanty, spotting character. If the case is more serious, pain and heavy bleeding are observed.
  2. It happens that during early pregnancy, minor periods occur, which appear due to mechanical damage to the vagina and cervix. For example, after a doctor’s examination and taking swabs, a girl may develop a small amount of blood.
  3. Minor bleeding may occur during sexual intercourse. This should not be a cause for concern, but to be completely sure it is necessary to undergo an ultrasound scan and also monitor the development of the embryo.
  4. Heavy periods during pregnancy can be observed due to ectopic development of the fetus. In this case, the fertilized egg attaches to the fallopian tube, and as soon as the fetus begins to grow, it becomes crowded, so the tube may rupture. This leads to internal bleeding, which is life-threatening. In almost all cases, the woman’s life can be saved, but her reproductive system may be truncated, because the fallopian tube cannot be restored.
  5. Menstruation during early pregnancy can occur if there are any genetic disorders or pathological conditions of the fetus caused by intrauterine diseases. It is almost impossible to save the child in such cases.

Damage to the uterus

Should I call the loop myself?

Lack of menstrual bleeding, breast swelling, a nervous state and early toxicosis may indicate the development of a new life inside you, sometimes not entirely desired. Then many begin to wonder: “How to provoke menstruation?”

As a rule, few people go to the doctor, because everyone is trying to find ways on the Internet using various herbs and drugs. Every woman understands that if menstrual bleeding begins, the pregnancy will stop, so they try by any means possible to purchase the necessary mixture or pills at the pharmacy.

This is a fundamentally wrong decision. First of all, you should consult a specialist who will tell you the most effective and safe method for you. For example, some people will benefit from an injection that will trigger menstruation. As a rule, oxytocin is used for this purpose, a medication that causes rapid contractions of the uterus.

No less effective drugs that can quickly induce menstruation are Pulsatilla, Postinor, Norkolut. It is also possible to induce menstruation with Duphaston or Utrozhestan.

Don't call yourself - it's dangerous

All of the above drugs are very dangerous for a woman’s health, because they radically change hormonal levels and can lead to subsequent infertility. That is why, before taking any medications, visit a doctor.

How to prepare yourself?

The key to the health of the unborn child is not only the physiology of the mother, but also her emotional state. All experts recommend thinking through some aspects in advance. If you have a feeling of doubt or discomfort, delay conception.

As sociological statistics show, antenatal depression is known to about 10% of pregnant women. Having thoroughly studied all the early signs of pregnancy before the start of a missed period, they are often unprepared for what awaits them, because they will no longer be able to control their body and life.

State of depression

The state of depression and despondency is transmitted to the growing fetus. To avoid negative consequences, you need to psychologically prepare yourself for this event.

Prenatal depression can be caused by:

  1. Inflated expectations. Some girls are sure that preparing for bearing a baby implies a kind of plan according to which everything goes. The only thing they will need is to monitor all aspects from the moment of conception to the day of birth.
  2. Unforeseen changes in the process of bearing a child can provoke high anxiety, stress or a nervous breakdown. It is necessary to accept in advance that it is impossible to control all aspects of life, so all situations that arise should be accepted calmly.
  3. Social interest. Not every girl is ready for the fact that her position will cause increased attention from people around her. Bad advice and intimate questions are sometimes asked not only by close people, but also by colleagues and acquaintances.
  4. As soon as the earliest signs of pregnancy appear even before your period is missed, you must immediately prepare yourself for the fact that you may have to learn to give the correct rebuff if the recommendations of strangers are inappropriate.
  5. Family problems. The fairy tale that a child is able to save a family is known to this day. Sometimes boundless faith in it leads to unjustified hopes. That is why, at the first signs of early pregnancy, even before your period, you need to solve all the problems with your partner in order to know for sure whether you need this child, whether it will be desired.

Let's look at a few reviews from women who had their periods at the beginning of pregnancy.

Even experienced women who care about their health can “miss” pregnancy by coming to see a doctor with the baby’s first movements. And the reason for this is “menstruation” during early pregnancy - discharge that is similar to the usual critical days, but has completely different reasons. How not to get into an awkward position and not “miss” an important event?

Early registration is important. A woman, knowing that she is “expecting a miracle,” protects herself more, tries to eat properly and nutritiously, and not take medications. All this keeps the baby healthy and gives him a chance to be born on time and without pathologies. In the presence of gross defects, already at the first screening ultrasound, many defects can be suspected, such as Down syndrome, pathological inversion of internal organs (umbilical ring hernia) and a decision can be made to prolong the pregnancy.

When does this happen

The discrepancy between the results of the examination, ultrasound and the date of the last menstruation always prompts the doctor to think that in the early stages the woman had discharge, which she considered to be the next “these days”. This happens especially often in girls with irregular and light menstruation. Pregnancy is not always planned, and not everyone jumps at the test when there is a delay of a day or two. The main reasons for such “periods” are as follows.

  • Abnormal ovulation. According to classical concepts, the release of the egg from the ovary occurs in the middle of the cycle and is accompanied by copious mucous discharge. In practice, this does not always happen. Often early ovulation occurs - on the third to fifth day of the cycle, late - on 21-25 or even double (at the beginning and at the end), all this leads to confusion for both the woman and the doctor, including with the duration of pregnancy. For example, when conceiving on the third day of the cycle, there may still be two or three days of bleeding. The woman is calm and believes that she is not pregnant. In fact, the fertilized egg is already actively developing. A similar picture occurs during conception on the eve of menstruation. The fertilized egg does not yet have time to “swim” into the uterine cavity, and the endometrium may be partially rejected. A woman mistakes spotting for scanty periods.
  • Anomalies in the structure of the genital organs. A woman does not always know that her uterus has developmental features. For example, bicornus (a defect in which the fusion of two rudiments of the genital organs does not occur). As a result, not the whole uterus is formed, but two horns in the area of ​​the bottom of the organ. The amniotic sac is implanted in one place, and the other horn undergoes the usual cyclic changes. It turns out that the woman is “pregnant”, and the fetal sac is successfully developing in one half of the uterus, while the other is “menstruating” at this time.
  • Bleeding due to implantation.“Menstruation” in the first month of pregnancy may be a consequence of the appearance of blood during the implantation of chorion. The amniotic sac strives to get inside the uterine cavity in order to calmly receive nutrients and develop further. During implantation, special enzymes are released that “dissolve” the vessels, allowing chorionic villi to penetrate the endometrium. This may be accompanied by slight bleeding and sometimes even small clots.
  • Ectopic pregnancy. Painful and scanty menstruation during pregnancy should always alert you to the abnormal location of the amniotic sac. Ectopic pregnancy occurs even in completely healthy women. Until the sixth to seventh day of gestation, the amniotic sac can normally be outside the uterine cavity (“wander”). Having secured itself in the fallopian tube, on the ovary, or even on intestinal loops (extremely rarely, but it happens), the embryo begins to develop. But the uterine cavity remains empty and the endometrium is gradually rejected, which manifests itself in varying degrees of severity and color of bloody discharge.
  • Threat of miscarriage. Most often, “periods” during pregnancy occur due to threatening spontaneous miscarriage. In this case, the difference in the number of discharges may be minimal. The condition is accompanied by nagging pain, nausea and other symptoms. In addition to the threat to a normal pregnancy, signs of an undeveloped pregnancy can occur in a similar way.
  • Abnormal chorionic implantation. Low placentation is a risk factor for the development of bleeding, which can threaten a woman’s life. Most often, this condition causes heavy periods during pregnancy. This is due to the fact that chorionic villi begin to penetrate into those places of the uterus that are not intended for this, for example, in the cervix.
  • Haemorrhoids. Hormonal levels already at the beginning of pregnancy can provoke an exacerbation of this pathology with the appearance of bloody discharge of varying intensity from the nodes. Sometimes they are so abundant that they can be mistaken for the beginning of menstruation.

During pregnancy, the cervix is ​​very vulnerable, especially if it has erosion or ectopia. Even normal sexual intercourse or taking smears can cause a slight discharge of blood during pregnancy.

How to distinguish periods from spotting during pregnancy

If you have even small doubts about the likelihood of conception, it is important to know how to distinguish “periods” during pregnancy from normal ones.

Determination of hormones in urine and blood

It is important to do a routine urine pregnancy test, purchased at a pharmacy. This is the most accessible and safe method that can be easily performed at home. But a negative test is not an indicator of absence of pregnancy. In the early stages it is not always informative. For a more reliable determination, it is recommended to take a blood test for the level of human chorionic gonadotropin, which shows the correct result already from the 10th day after fertilization. If it is negative, there was no conception; if it is positive, there was.

If a woman monitors her basal temperature, she can also reliably judge whether menstruation is possible or whether it is discharge during pregnancy. A temperature above 37°C in the rectum is direct evidence of fertilization.

How you feel

Pregnancy for many women is accompanied by other symptoms. The main ones are:

  • nausea, vomiting in the morning;
  • increased sensitivity to odors;
  • engorgement of the mammary glands;
  • increased sensitivity of the nipples and areola area of ​​the breast;
  • mood changes - swings or tearfulness;
  • the appearance of weakness, increased fatigue.

If the cause of abnormal discharge is pregnancy, these symptoms will also persist.

By the nature of the discharge

In most cases, discharge that can be mistaken for “menstruation” during pregnancy is of an unusual nature, which is why it raises doubts and suspicions in the woman. But reviews confirm the fact that when menstruation is usually scanty, women often do not notice the difference. However, you should pay attention to the following points:

  • if the discharge is insignificant;
  • if they last a day or two;
  • if it started earlier, for example, a week;
  • if they are unusually large and clotted;
  • if they appeared after a delay.

If in doubt: algorithm of actions

If an “interesting situation” cannot be ruled out, and there is bleeding, you should go to the doctor. In no case should you think about folk remedies or take pills in order to intensify your periods and cause termination of pregnancy as a continuation of the miscarriage that has begun.
It is also best not to try to stop the bleeding with herbs or medications. This will not help stop the discharge, but can negatively affect the health of both the woman and the fetus. The correct algorithm of actions is as follows.

  • Remember the date of your last menstruation. This will help you understand whether it is bleeding or pregnancy is possible.
  • Take a urine pregnancy test. Even a weak second line is a positive result.
  • Remember possible provocateurs. There may have been sexual contact, stress or physical activity that can cause discharge.
  • Perform an ultrasound. It is necessary to do this only if the discharge is spotting and nothing else is bothering you, and after that you should consult a doctor with the result of the examination, which will facilitate the diagnosis.
  • Go to the hospital. If the discharge is heavy or there is abdominal pain, you should seek medical help as soon as possible. If you are in normal general health, you should make an appointment as early as possible (within two to three days).

The question of whether menstruation can occur during pregnancy can be answered unequivocally: gestation and the normal menstrual cycle are two contradictory concepts. Any bleeding during pregnancy is a pathology that requires medical supervision and treatment. Therefore, if you have any doubts about your own condition, you should consult a doctor.

Print

A woman’s body is designed in such a way that in the absence of pregnancy, an unfertilized egg becomes the cause of menstrual periods. The discharge of blood in the second half of the cycle may indicate conception and not be menstruation.

Pregnancy if you have your period is possible in extremely rare cases. Bloody discharge in this case indicates endometrial detachment and the threat of miscarriage. Even more rarely, it is possible for two eggs to mature - one develops, the second dies and causes menstruation on time.

The logic of many women is clear: if you have your period, it means you are not pregnant. However, possible fertilization of the egg cannot be ruled out.

There are a number of conditions under which they can go:

  1. Time of implantation of the fertilized egg. At 2–4 weeks after fertilization, the fertilized egg implants and damages blood vessels, which cause spotting that vaguely resembles menstruation. More often, this process occurs without bleeding; in rare cases, a woman may notice, during her period when her period should have begun, small brownish spotting for 1–3 days in a row. This is a harmless condition that does not require medical intervention.
  2. The period when the egg has not yet implanted into the lining of the uterus before the onset of menstruation. In this case, scanty discharge may be observed. The whole process takes from 1 to 2 weeks, especially when conception occurred towards the end of the second half of the cycle. That is, menstruation begins exactly at the time when the fertilized egg “looks” for a place for implantation.
  3. The maturation of two eggs at the same time is the rarest case when a woman can become pregnant at the onset of menstruation. The eggs develop in different ovaries. One is rejected, stimulating the onset of menstruation, the second is fertilized and continues to develop.
  4. Hormonal imbalance. An excess of male hormones and a lack of progesterone can cause slight bleeding during conception.

The nature, color, and volume of this discharge determines whether such “periods” can threaten pregnancy. A small brownish smear most often does not pose a threat to the development of the fetus, while heavy bleeding is a symptom of miscarriage.

Many women very often wonder whether they can go. However, in this matter it is better to immediately contact a specialist to avoid serious consequences.

Will implantation occur if fertilization has occurred?

So-called implantation bleeding, which is often mistaken for normal periods, can occur if implantation occurs on the day it starts or a couple of days before.

Such bleeding is considered normal and occurs when the embryo naturally implants into the uterine mucosa. That is, it depends on the timing of implantation of the egg whether there can be a pregnancy if menstruation occurs (more likely, a spot).

Implantation does not occur immediately after fertilization of the egg. It moves through the tubes into the uterine cavity, after a few days it attaches, and the fetus begins its development.

If conception has occurred, but the egg has not yet implanted, menstruation may occur. The test will be negative, and only when your period has passed is a positive result possible.

Types of bleeding during implantation

There are two options for bleeding during implantation:

  1. In the process of implantation of the egg into the endometrium, approximately a week after conception (on the 22nd day of the cycle), there is still no delay, but minor spotting may appear. This is a rare case in medical practice.
  2. Most often, implantation bleeding occurs in the 6th week after the first day of the last menstruation. Just at this time, rapid growth of the chorion occurs, which corresponds to a pregnancy period of 4 to 5 weeks. This condition is observed in almost a quarter of expectant mothers and is often perceived by them as an ectopic pregnancy or miscarriage. Stops after 2–4 days.

Only in rare cases, slight bleeding can mean that the pregnancy is ectopic or there is a threat of miscarriage. If there is heavy bleeding, we can say that there was a pregnancy, but it was interrupted for some reason.

Implantation is also possible on the first day of the onset of regula. If fertilization occurs 5–6 days before its onset, then the embryo is implanted on the 1st day of menstruation. The reasons for this are the long stay of the sperm in the fallopian tubes and the displacement of ovulation. In this case, the woman became pregnant if her period came on time, towards the end of the second half of the cycle or immediately before the start of her period.

What do periods mean if you are pregnant?

Whether menstruation can occur after conception depends on many factors: inflammatory processes in the woman’s genital organs, hormonal levels, and the location of pregnancy (in the uterus or outside it).

Fertilization at the same time as menstruation can be a dangerous symptom for the woman and the fetus. Menstruation during pregnancy often indicates pathologies such as:

  1. Unsuccessful embryo attachment. This may cause a small amount of blood to leak over a period of several weeks. As a rule, this occurs due to the presence of myoma/fibromyoma.
  2. Hormonal imbalance, often an increase in the level of male hormones, as well as a decrease in the concentration of progesterone.
  3. Rejection of one embryo from a couple. It rarely happens that two fetuses develop, after which one of them stops developing and is rejected, causing bleeding.
  4. Abnormalities in fetal development during the intrauterine period can cause miscarriage.
  5. Presence of an ectopic pregnancy. In this case, they are associated with the development of the fetus in the abdominal cavity, tubes, and cervix. As the embryo grows, soft tissue ruptures with damage to blood vessels and bleeding.

In general, the state of the mother’s reproductive system determines whether menstruation can occur upon conception. Normal levels of female and male hormones, the absence of chronic diseases of the genital organs, stress, and trauma guarantee the physiological attachment and further development of the egg.

Bleeding that looks like menstruation when tested positive is a serious cause for concern. If the bleeding increases, as during normal periods, and the color is bright red, you should consult a gynecologist.

You can suspect that fertilization has occurred if, instead of regular periods, a woman develops a brownish smudge that ends in 1–2 days. A test carried out over such a short period of time often gives a false negative answer, since the level of hCG in the body is still negligible.

In any case, if, it is necessary to repeat the test and consult a doctor.

One might think that the expression “getting your period during pregnancy” might be an oxymoron. The generally accepted belief is that once a woman discovers she is pregnant, her menstrual cycle immediately stops. The basic idea is that a woman is only pregnant if she has a missed period, so she shouldn't be pregnant if she has one. Right? In this article we will try to answer this and many other questions.

Can I get my period during pregnancy?

Every now and then there is a story about a woman who didn't realize she was pregnant until she felt contractions. For most women, this sounds completely impossible! Wouldn't you notice the absence of menstrual cycles? Perhaps nausea, or at least a growing belly, will attract your attention.

When asked why they didn't understand or what they were expecting, some responded, "I was still having what I thought was my menstrual period, so I didn't think it could be pregnancy." How is this possible?!

We know that some women experience bleeding during pregnancy, but how can they confuse it with their period?

Sometimes during pregnancy there really is a period that can be confused with menstruation

The menstrual cycle is divided into four parts:

  • Your period is when you bleed;
  • Follicular phase - when the egg begins to mature for ovulation;
  • Ovulation is when your body releases a mature egg;
  • The luteal phase is the time after ovulation that lasts until the eggs are fertilized or the unfertilized egg dies and results in menstruation.

Menstruation is more than just bleeding. They occur when your progesterone drops because no fertilized egg is implanted.

Can you have a regular menstrual cycle and be pregnant?

There are a sufficient number of reasons for detecting bleeding during pregnancy. Some of these causes are serious and require medical treatment, and some are not.

There are cases where women experience regular menstrual cycles even though they are pregnant. This can occur as a result of conception close to the time of the next menstrual period and can cause serious confusion in terms of timing.

The baby's gestational age and due date are usually calculated based on the date of the last menstrual period.


Sometimes menstruation is confused with an ectopic pregnancy, and this is very dangerous.

An ectopic pregnancy, in which an embryo implants somewhere outside the uterus, most often in the fallopian tube, can cause bleeding similar to menstruation. If you experience cramping and bleeding during early pregnancy, urgent medical attention is needed. If the expectant mother is hospitalized at the right time, perhaps the child will be saved.

Some things end before they really begin

It is a startling fact that only about 25 percent of pregnancies actually result in live births. Most expectant mothers who have no experience do not even have time to understand the fact that they are pregnant. Unfortunately, it often ends in miscarriage.

Due to the risk of an ectopic pregnancy, it is recommended that you notify your doctor promptly if you are concerned that a miscarriage may occur. Most pregnant women do not receive proper care from medical personnel.

What causes bleeding?

Implantation bleeding - fertilized implants from eggs. As it burrows into the uterine lining, some women experience a little spotting or bleeding. This bleeding usually occurs when the embryo attaches to the wall of the uterus. This type of bleeding usually occurs five days after conception, so it is easy to understand why a woman would confuse this bleeding with her menstrual cycle and may have difficulty determining when her last menstrual period was. Implantation bleeding is not that common and is usually nothing more than a small spot or pinkish-red mucus.

Breakthrough bleeding - During the early stages of pregnancy, your body produces progesterone and other hormones that prevent your body from triggering the onset of your period. Breakthrough bleeding usually occurs during the first cycle after conception and may continue into the first trimester. In this case, it is important to note that any bleeding after the first bleed will not occur in a timely, predictable manner like your period. This will be sporadic bleeding that will vary in flow. Multiple periods of time, whether irregular for you or not, are unlikely to be bleeding due to pregnancy.

Placental bleeding - placenta previa is when the placenta is close to, partially or completely covering the cervix.

Placental abruption means that the placenta is partially or completely separated from the wall of the uterus.


Placental abruption is a dangerous condition that can kill both the baby and the expectant mother.

Placental lakes are expanded spaces in the placenta filled with maternal blood. These and several other placental complications can often cause painless vaginal bleeding in the second or third trimesters.

Special circumstances

However, not all women have a standard 28 and 32 day cycle. In less common scenarios, a woman with a shorter menstrual cycle (eg, 24 days) may have seven days of bleeding, have intercourse on the last day of bleeding, and ovulate three days later. Since the sperm lives for three to five days, she can definitely get pregnant.

Additionally, some women experience breakthrough or bleeding.

Mild lower abdominal cramps, spotting (spot implantation, a fairly common cause of one-time bleeding), breast tenderness and moodiness, and having unprotected sex during your period. These symptoms may appear as early as 2 weeks after ovulation.

Other, more common pregnancy symptoms that may help determine if you are pregnant include: nausea, vomiting, and extreme fatigue.

Ultrasounds can help determine the cause of bleeding

While blood may appear from time to time while you are carrying your baby during pregnancy, it does not always indicate the onset of your period. Any blood that appears may be due to implantation of a fertilized egg or a miscarriage, infection, or upcoming contractions.


Any discharge, especially bloody discharge, that differs in composition or timing from menstruation should alert a woman

Pregnancy, while you are taking the pill, is often accompanied by bleeding, which can be confused with the menstrual cycle. Many women who are on the pill have several episodes of bleeding before they realize that something is not quite right. In such cases, the woman usually cannot tell her doctor exactly when her last actual menstrual period was, and an ultrasound is required to provide the mother and doctor with an approximate date.

During pregnancy, there are many different moments when the expectant mother experiences blood loss in the vagina. The causes of this bleeding can range from harmless to life-threatening, so it is important to know what types of bleeding can occur. The doctor needs this to diagnose the cause of any bleeding in order to save the patient from this problem. The main goal is not to harm the fetus.

Early pregnancy

You may experience blood loss before you even know you are pregnant. Namely, implantation bleeding can occur when a fertilized egg enters the bloodstream of the uterus.

Miscarriage most often occurs early in pregnancy and is often accompanied by bleeding. Depending on the week in which the miscarriage occurs, it may seem like just a normal menstrual cycle that arrived a few weeks late. Women experience varying amounts of blood loss during a miscarriage. Additionally, the cramps felt before and during a miscarriage can vary significantly. In general, the longer the pregnancy, the more blood and cramps will accompany the miscarriage, but this depends on each woman’s body individually.


Bright scarlet discharge may be a symptom of miscarriage

It's natural to worry if you have spotting or bleeding. Tell your doctor or midwife because bleeding can sometimes be worrying. Unfortunately, sometimes bleeding can be the first sign of miscarriage. If so, it probably won't look like a normal period. The pregnant woman will likely have severe abdominal cramps and much heavier bleeding.

If you notice dark and watery bleeding, contact your doctor immediately. You may have an ectopic pregnancy that requires prompt treatment.

Bleeding during early pregnancy may make it difficult to work as intended. Midwives and doctors often initially use the first day of your last period to estimate when conception occurred. If there is no doubt, measuring your uterus can help you determine your gestational age.

Ectopic pregnancy is the most serious condition that causes bleeding in early pregnancy. Both miscarriage and ectopic pregnancy cause the loss of a baby, but an ectopic pregnancy can be very dangerous for the mother and it can reduce her chances of carrying another child in the future. While diagnosis of this type of pregnancy should be made, ideally before the fallopian tube with growing ovarian ruptures, receiving immediate medical attention after a rupture can help minimize risks to the mother.

Late bleeding

One in 10 women will experience vaginal bleeding during the third trimester, and this may be a sign of a more serious problem. Bleeding in the last few months of pregnancy should always be reported to a healthcare professional as soon as possible. First, you need to understand the difference between spotting and bleeding: spotting occurs when there are a few drops of blood on your underwear, but not enough to cover your panty liner. Bleeding is a heavier flow of blood.

Infections remain a cause of bleeding throughout pregnancy. At any stage, you can easily become infected. You can also try to minimize the risk of infection.

Another reason you may be bleeding late in pregnancy is that you are about to go into labor. "Soon" can mean in a few minutes or in a few weeks. If you experience premature contractions, your doctor must admit you to the hospital.


Is it worth going to the doctor if you have heavy bleeding for a long time - definitely “yes”!

If you are already 37 weeks pregnant and notice a little blood, the amount and color will help you determine if you need to seek medical attention immediately. If you have a small amount of pinkish/bleeding discharge and you are over 37 weeks, there is no reason to panic. If you see bright red blood, whether you're already 37 weeks or not, call your doctor. You may be going into labor, but this could be a much more serious complication that requires urgent hospitalization.

Conversion of the placenta (low placenta) or placental abruption leads to bleeding. Placental deposition is very dangerous for the baby and leads to a decrease in the oxygen supply to the baby.

Erroneous menstruation during pregnancy

While there are many reasons why pregnant women lose blood during pregnancy, none of them are actually menstruation. Postpartum bleeding is also not considered menstruation.

It is always important to diagnose and understand why the bleeding occurred in order to begin treatment. Some causes of pregnancy bleeding are benign, while others are dangerous for the expectant mother and fetus. They need specialized help.

If you are already sexually active, then you are strongly recommended to visit a gynecologist at least once every six months. Also pay attention to how your periods are going. This is a very important process, a lot depends on it. If you do not have it regularly, then this indicates a hormonal disorder. It will be difficult for you to determine the presence or absence of pregnancy.

What's the difference between menstruation and pregnancy?

The easiest way to differentiate between periods and pregnancy-related bleeding is to take a test to determine whether you are pregnant or not. If it's negative, it means your period is out of whack, and if it's positive, you should head to your OB/GYN.
