Causes of menstruation in early pregnancy. Pregnancy through menstruation: how to recognize the signs. The nature and color of menstruation during pregnancy is normal

Interruption of the menstrual cycle after conception is the norm, a natural process, the violation of which can lead to various consequences. Why do you sometimes get periods during pregnancy?

Menstruation during pregnancy is not uncommon, but a reason to consult a gynecologist. After all, this may be a sign of a serious hormonal or other disorder that will prevent you from bearing a child.

Menstruation appears during pregnancy early stages, most often, during the first month. This is facilitated by various failures in the maturation of eggs (for example, in both ovaries simultaneously), multiple pregnancies with the prospect of rejection of one of the embryos, hormonal disorders, and the presence of diseases such as fibroids and endometriosis.

The reasons for the release of bloody mucus in the early stages may be implantation of the fertilized egg into the wall of the uterus, sex, or damage to the vaginal mucosa during a gynecological examination.

Cycle duration

Can menstruation occur after conception and when does it stop? Strictly speaking, menstruation and pregnancy are incompatible; the cycle should stop immediately after implantation of the fertilized egg into the uterine wall. And if this does not happen, it means that the fertilized egg, formed at the end of the previous cycle, simply has not yet had time to reach its destination. Usually it takes from 7 to 15 days for attachment, during which period menstruation may occur.

How to distinguish a cycle from bleeding?

How to distinguish spotting from menstruation, and why can menstruation occur during pregnancy? With regular sexual activity, without the use of contraceptives, fertilization of the egg in healthy woman almost guaranteed.

Signs of pregnancy during menstruation in the early stages may include:

  • the onset of the cycle is significantly earlier or later than the due date;
  • the discharge is not abundant, even scanty, without the usual clots, indicating detachment of the endometrial layer of the uterus;
  • the color can vary from bloody pink mixed with mucus to red-brown;
  • unusually short running cycle.

All these signs of pregnancy after menstruation are evidence that the discharge is not menstruation at all.

As for the bloody mucous discharge that sometimes accompanies the early stages of conception - their cause is most often mechanical damage to the vaginal walls during sex or after gynecological examinations, such discharge is not dangerous. Heavy bleeding of brightly colored blood should be alarming, which, being a sign of rupture of large vessels, requires immediate medical attention.

In the first trimester

Menstruation at the beginning of pregnancy can last up to 11 - 12 weeks, most often this is caused by hormonal disorders: taking birth control pills, hormone imbalance caused by various endocrinopathies, viral and infectious diseases, stress.

Other reasons for menstruation in early pregnancy may include:

  • implantation of the fertilized egg into the endometrial layer of the uterus, which causes minor vascular damage. As a result, scanty discharge appears that does not threaten the development of the embryo;
  • fertilization occurred at the end of the cycle, and the egg did not have the opportunity to attach to the wall of the uterus, such “periods through the fetus” are real, and they can only happen in the first month of pregnancy, while the body has not yet begun to rebuild;

  • Can there be pregnancy with real menstruation, and in what other cases? A very rare occurrence of almost simultaneous maturation of eggs in different ovaries. In this case, when the first is fertilized, the second is rejected;
  • the attachment of fertilized eggs, how many there will be, does not matter. One of them is rejected, causing bleeding;
  • ectopic, in which the discharge is easy to distinguish from normal ones - they look like brown clots and are accompanied by sharp pain;
  • the attachment and growth of an unfertilized egg, before spontaneous rejection, provokes regular bloody-mucous discharge.

Menstruation in the first month of pregnancy may be no different from real menstruation and sometimes continues until the end of the trimester, but it is very scanty.

What periods during pregnancy in the first trimester can be considered dangerous? Heavy bleeding with pain or frequent regular traces of blood indicate a serious pathology, for example, a threat of miscarriage. In general, pregnancy and menstruation are incompatible; any bleeding in this position is a reason to consult a doctor.

In the second trimester

You can still put up with spotting in the first trimester, since most of it does not pose a threat, but do you have periods during pregnancy in the second trimester? The appearance of blood at this moment is a direct threat of miscarriage. Its reasons may be:

  • presenting position, when the walls of the uterus cannot hold the incorrectly lying placenta in a fixed position. Ruptures occur, resulting in bleeding;
  • partial or complete rejection of the placenta before birth;
  • threat of abortion and frozen fetus;
  • bleeding from the vessels of the fetal umbilical cord;
  • rupture of uterine tissue. Such bleeding occurs due to the presence of a postoperative scar, chorionepithelioma, thinning of the uterine walls due to numerous births and abortions.

Anyone who has had their period during pregnancy knows that any bleeding in the second trimester is a reason to immediately go to the hospital. If you contact us in a timely manner medical institution in 95% of cases, miscarriage and fetal death can be prevented.

In the third trimester

Can menstruation occur during pregnancy in the third trimester, and what causes bleeding? Discharge during this period is a threat of interruption; their cause can be any acute infectious or viral disease, disorder hormonal levels, severe nervous shock, injuries, bruises, placental rejection and bleeding from the vessels of the fetal umbilical cord.

During pregnancy, menstruation can be triggered by other pathologies:

  • an enlarging fetus can cause the development of a serious disease - varicose veins of the uterus, and later and provoke rupture and bleeding from damaged vessels;
  • cervical erosions that are not treated in time may manifest themselves as minor but regular bleeding;
  • extremely rare cases - bleeding during pregnancy can occur due to intrauterine polyps or cervical cancer.

Menstruation and pregnancy in the third trimester are incompatible and may be a reason to maintain or terminate for medical reasons. If at this moment your period begins, especially heavy periods, this can be very dangerous for the life of the mother and child.

What is the danger?

Menstruation during early pregnancy is not always dangerous, only in the later stages of gestation. In the second and third trimester, with very rare exceptions, they indicate pathological changes in the body and pose a danger to the baby and the life of the mother. For example, with varicose veins there is a chance to provoke rupture of fairly large vessels of the uterus and it is extremely difficult to stop such bleeding.

To be precise, all bleeding that occurs after conception cannot be called menstruation: they have a completely different mechanism of occurrence. Although real periods may occur in the first month of pregnancy, due to fertilization at the end of the previous cycle.

During pregnancy, there are periods triggered by mechanical damage to the vaginal walls; they can also be considered harmless, provided that microcracks are not infected.

More reasons

Pathologies that can trigger the appearance of menstruation during pregnancy:

  • abnormalities in the development of the uterus (for example, bicornuate), in which it is very difficult to become pregnant and bear a fetus;
  • spicy infectious diseases, such as syphilis, tuberculosis;
  • various hormonal disorders and endocrinopathies;
  • bleeding disorders;

  • the presence of varicose veins of the uterus;
  • congenital pathology of fetal development;
  • hypovitaminosis;
  • consumption of some medicines that can cause uterine contractions;
  • ectopic and multiple pregnancy;
  • placenta previa;
  • chorionepithelioma;
  • severe nervous shock, shock, stress.

The cause may be household injuries due to falls and bruises.

Symptoms

Is pregnancy possible during menstruation, or is it impossible? At this moment, extremely unfavorable conditions for the survival of sperm are created in the woman’s genital tract, so conception becomes impossible.

But is it possible to be pregnant during menstruation, and how can you tell whether you have a period or discharge? During menstruation, the breasts usually swell quite painfully and the lower abdomen pulls. If these symptoms are absent, then the following can be considered a sign of pregnancy after menstruation:

  • scanty, brownish discharge;
  • “menstruation” is always painless;
  • came much earlier or later than expected;
  • ended quickly;
  • occurs only during the daytime.

Features of physiology

Can menstruation occur during pregnancy or is this a pathology? Why do I have my periods and what causes the bleeding? Regularly in female body The egg ready for fertilization matures; during its maturation, the uterus prepares for the attachment of the fertilized egg, growing a special layer of cells. If fertilization does not occur, the egg and the layer of endometrial epithelium are released with menstruation.

When fertilization has occurred, the body begins to undergo hormonal adjustments so that the fertilized egg is fixed in the uterine wall, and no factors provoke its rejection. Thus, to the question of whether it is possible to be pregnant if you are menstruating, the answer is yes, but only in the very early stages, because menstruation after conception is more of a pathology than the norm.

How do you know if the cycle has not stopped?

Can pregnancy occur after menstruation? How can I find out? Of course, by purchasing a test. But sometimes this is not a guarantee. You can confirm the presence of an embryo with 100% certainty if you take a test for human chorionic hormone (hCG), which begins to grow literally from the first week. And with normal fetal development, it increases 1.5 times every 2 days.

Disputes about this issue continue among expectant mothers. Some women claim that they menstruated before giving birth. This is a misconception: menstruation and pregnancy are incompatible.

Can you have periods during pregnancy?

To answer the question, let’s refresh our knowledge of female physiology. Once a month, an egg matures in the ovary, which is necessary for fertilization. If conception does not occur, it is destroyed, the functional layer of the endometrium is rejected, and spotting occurs. If conception has occurred, the body prepares for implantation of the embryo by rearranging its hormonal levels. The functional layer in the uterus is not rejected, and menstruation stops during pregnancy.

Where does the blood come from then? With progesterone deficiency (progesterone is a hormone), bleeding appears on the days when menstruation begins on schedule. Doctors call this phenomenon “false menstruation.” Sometimes spotting continues for 3-4 months, although the fertilized egg develops in the uterus.

The cyclical nature of bleeding misleads a woman. She does not even suspect that she is expecting a child, and finds out about the pregnancy too late. This is dangerous for mother and child, because a woman, not knowing that she is expecting a child, continues to lead her usual lifestyle: doing hard work, eating poorly, drinking alcohol, taking medications that are not recommended during pregnancy. It is difficult to determine the due date; sometimes a woman finds out that she is having a baby at 4-5 months, when it is impossible to terminate the pregnancy.

Even intense false menstruation does not affect the development of the fetus and embryo: the baby will not be born sick or underdeveloped. But if the cause of bleeding lies not in hormonal disorders, but in organic causes, it is difficult to carry the child to term.

If the bleeding occurs because the fertilized egg implanted outside the endometrium of the uterus (ectopic pregnancy), the embryo is removed to save the woman. Sometimes the oviduct and ovary are removed.

Menstruation during early pregnancy

There are many reasons for such allocations:

  • During conception, sometimes the egg remaining from the previous cycle is fertilized, that is, the new one has already been released, and the old one has not yet died. This occurs with short (21-24 days) menstrual cycles. As a result, in the first month after fertilization, full menstruation occurs during pregnancy. From conception to implantation it takes 7-14 days. If premenstrual processes have begun in the endometrium, critical days begin and pass as in other months.
  • Sometimes two eggs mature during a cycle. If one is fertilized and implanted in the endometrium, and the other is not, menstruation occurs during pregnancy. Since critical days are frequent in the early stages, in obstetrics it is customary to count the development of a child not from the expected conception, but from the date of the last menstruation.
  • Sometimes women mistake implantation bleeding, which occurs when the embryo attaches to the endometrium of the uterus, as critical days. It occurs on or before the next menstrual period. With implantation bleeding, a small amount of blood is released, the bleeding lasts one to two days.
  • False menstruation in the first months occurs in women who took before pregnancy birth control pills. Until the body adapts to the natural hormonal levels, bleeding within the period corresponding to critical days will not stop.

Bleeding during pregnancy can be dangerous.

Since the body in the early stages of pregnancy does not have time to adapt to the changed hormonal levels, progesterone deficiency and excess androgens occur, accompanied by spotting. This is dangerous for the embryo, which is still small and not sufficiently strengthened in the uterus.

Menstrual-like bleeding from the second month of pregnancy is a common sign of a threatening miscarriage caused by rejection of the embryo due to immune disorders in the mother. The woman’s body perceives the embryo as a foreign body, kills and expels it.

A serious complication accompanied by periodic bleeding from the genital tract is a hydatidiform mole. With this disease, the chorionic villi of the fetal egg degenerate into vesicles that merge into “clusters”. Cystic formations also appear in the ovaries (luteal cysts). From the second month of pregnancy, a woman begins to have periodic bleeding, reminiscent of discharge during her period. Mole bubbles come out along with the blood. This happens until the formation, consisting of small cysts, comes out. The disease is dangerous due to the development of a severe complication - chorionepithelioma - a malignant tumor that early metastasizes to the brain, liver, kidneys, and lungs.

Heavy periods during pregnancy

In the first month of pregnancy, menstruation can be heavy or scanty. It depends on the woman's hormonal background. Subsequently, blood flow stops. If this does not happen, you should consult a doctor and find out the cause of menstrual-like bleeding.

Blood during pregnancy is caused by:

  • beginning or threatening miscarriage, including those caused by progesterone deficiency. Sometimes hormonal imbalance during pregnancy manifests itself as heavy false periods;
  • hormonal deficiency, which causes heavy menstrual-like bleeding;
  • frozen pregnancy, when the embryo develops with a delay or dies. This condition occurs with congenital abnormalities of embryo development, severe hereditary pathologies, or increased uterine tone. More often, the embryo “freezes” at 3-4, 7-8, 16-18 weeks.
  • placental abruption, in which the “baby place” is separated from the walls of the uterus. The released blood flows out through the genital tract or remains under the placenta, provoking new bleeding;
  • at multiple pregnancy One embryo may not develop or may die. This is also accompanied by bleeding;
  • placenta previa, when it is located close to the uterine os. As the fetus grows, bleeding occurs, which the expectant mother mistakes for heavy periods;
  • pathologies of the uterus in which the course of pregnancy is difficult: one-horned, two-horned, saddle-shaped or baby;
  • endometriosis and benign tumors of the endometrium and myometrium, including: fibroids, fibroids, cysts, polyps. With these diseases, menstrual-like bleeding during pregnancy is not uncommon;
  • bleeding occurs due to overexertion, stress and elevated temperature, leading to hormonal imbalance, increased uterine tone, miscarriage or “freezing” of embryo development.

It is easy to confuse the heavy bleeding that occurs during an ectopic pregnancy with menstruation. A miscarriage follows the principle of a tubal abortion. Excreted from the genital tract large number dark blood with fragments of the deductive membrane.

You should immediately consult a doctor if heavy bleeding during pregnancy is accompanied by:

  • severe pulling or cutting pain in the lower, right or left abdomen;
  • nausea, salivation, vomiting;
  • fainting, severe headache, weakness, dizziness, pale skin and increased heart rate;
  • increase in body temperature.

Heavy bleeding is a cause for serious concern. Without the use of emergency measures, the fetus faces intrauterine death, and the woman faces serious blood loss. Ectopic and frozen pregnancies require urgent surgical treatment.

How to distinguish periods during pregnancy from normal ones

The duration and intensity of bleeding changes, the woman understands that changes are occurring in the body. False menstruation is caused by other reasons not related to the mechanism of normal menstruation:

  • The menstrual cycle changes - it shortens or lengthens, sometimes bleeding appears twice a month.
  • The discharge becomes scanty, and “spotting” or light pink leucorrhoea is observed. Sometimes bright scarlet or dark red blood appears with clots or mucous fragments of the deductive membrane.
  • The number of critical days also changes. False periods end 1-2 days earlier, but sometimes, on the contrary, a woman bleeds for a week.
  • No symptoms premenstrual syndrome. After critical days, the mammary glands remain enlarged, but the swelling does not go away.
  • In some cases, false periods are difficult to distinguish from physiological ones. In doubtful cases, using a pregnancy test or donating blood for hCG - human chorionic gonadotropin - will help.

Pregnancy is correctly diagnosed by a doctor using an ultrasound. The condition of the placenta and fetal membranes, the place of attachment of the embryo and the approximate date of birth are determined.

Menstruation, no matter what month it starts, is a good reason to visit a gynecologist, even if nothing hurts and the pregnancy is easy. By relying on “maybe”, you can miss an ectopic and frozen pregnancy, miscarriage, hydatidiform mole, previa and placental abruption. You should not make a diagnosis yourself. Only a doctor can determine the cause of menstrual-like bleeding. The gynecologist will conduct an examination and, if necessary, prescribe surgical or conservative treatment.

Usually a delay in menstruation of several days indicates possible pregnancy. It is on this basis that a woman first diagnoses herself, after which she either turns to a specialist or conducts a test at home. But sometimes a woman is already pregnant, and her periods continue to go according to schedule, and the expectant mother does not even think about conception. Despite any arguments, pregnancy during menstruation is possible, this has been proven in both scientific level, so life examples. Which cases of menstruation during pregnancy are considered normal, and which carry a health hazard?

Experts' opinions

If a woman has her period in the first month of pregnancy, as a rule, experts do not see anything wrong with it. This may be due to conception at the end of the cycle. In this case, the fertilized egg does not have time to gain a foothold in the uterus, and the body, accordingly, does not respond with any reaction to the presence of a new body, so the next cycle occurs on time.

In some cases, periods come early. Pregnancy with this phenomenon proceeds normally, and menstruation should stop in the next cycle. If they continue, then the necessary examination should be carried out.

Summarizing all the available facts, as well as analyzing the opinions of specialists and women who experienced menstruation during pregnancy, we can definitely say that the presence of the first menstruation cannot indicate pathology or any diseases that can cause harm to health. They are considered normal during conception in the second half of the cycle. Also, do not confuse bleeding with menstruation. To do this, it is worth remembering the signs of both phenomena, which are described in detail in this article.

But still, to prevent possible complications, as well as for your own peace of mind, it is more advisable for every woman who continues to have periods during an expected pregnancy to visit a specialist who will carry out all necessary examinations and prescribe, if necessary, the correct treatment or prevention.

Even the most experienced women who monitor their health can skip pregnancy and come to an appointment with a specialist already from a baby. This is due to menstruation in early pregnancy. They are discharge that looks very similar to the usual critical days, but their reasons are completely different.

Very important has early registration of pregnant women. Knowing about her situation, the woman does not take medications, tries to eat well and properly and protects himself more. If there are serious developmental defects, then at the very first screening ultrasound diagnosis many defects can be seen and a decision can be made to continue or terminate the pregnancy.

When do you get your period during pregnancy?

This is very often observed in girls with light and irregular menstruation. Pregnancy is not always a planned event, and not everyone runs to the pharmacy for a test if the delay is a day or two.

The causes of such discharge during pregnancy are:

The cervix is ​​very vulnerable during pregnancy. This is especially true in cases with ectopia and erosion. Even taking smears or having sexual intercourse can cause small amounts of blood to be discharged during pregnancy.

How long can periods last during pregnancy?

Delayed menstruation is the most common sign of pregnancy. But there are exceptions to the rule when menstruation does not stop. Most gynecologists do not consider menstruation in the first month after conception a sign of danger or a pathology. The reasons lie specifically in the fertilization of the egg and the subsequent implantation of the woman’s fertilized egg.

It also happens that in the early stages they do not stop going throughout the entire first trimester. Here you cannot do without an examination by a specialist. First, it is necessary to eliminate the threat of miscarriage and establish the reason why the woman’s body does not respond to conception.

Experts identify several reasons for this phenomenon:

Many women are interested in how many months menstruation can last during pregnancy and until what period is this considered normal. Doctors say that this phenomenon can last no more than 4 months. But even if when carrying a baby There are no pathologies, then monthly bleeding should still alert the doctor and the expectant mother.

How can you tell the difference between spotting and menstruation?

If there are any doubts about the beginning and normal course of pregnancy, it is worth knowing how menstruation when carrying babies, distinguish them from ordinary ones.

Determination of hormones in blood and urine

It is very important to conduct a urine pregnancy test by purchasing one from a pharmacy. This method is the safest and most accessible. It can be done at home without any problems. But if the result is negative, this does not mean that you are not pregnant. It is not always informative in the early stages. For a more accurate result, it is worth taking a blood test to measure the level of human chorionic gonadotropin. You can find out the correct result already on the 10th day after conception. If it is positive, then conception has occurred, but if it is negative, then no.

If a girl watches, then she will also be able to determine whether it is menstruation or discharge during pregnancy. Direct evidence that fertilization has occurred is a temperature in the rectum above 37 degrees.

How I feel

For many women, pregnancy is accompanied by symptoms such as:

These symptoms will persist even with abnormal discharge during pregnancy.

By the nature of the discharge

In most situations, discharge that can be confused with menstruation during pregnancy is unusual. It is for this reason that they arouse suspicion and doubt in a woman. But based on reviews, one can judge that if monthly discharge was normally meager, then women don’t notice the difference. You need to pay attention to the following factors:

  1. If spotting appears after a delay.
  2. If they are clotted and unusually abundant.
  3. If they started earlier than expected.
  4. Lasts only 1 or 2 days.
  5. Minor.

Algorithm of actions when in doubt

If a woman does not rule out that she may be pregnant, but she has discharge, then she immediately needs to visit a specialist. Under no circumstances should you take any medications or use traditional methods in order to intensify menstruation and cause termination of pregnancy, as a continuation of the miscarriage that has begun.

It is better not to try to stop the bleeding with medications and herbs. This will not stop the discharge, but it may have a negative effect on the health of the fetus and the expectant mother. The most correct algorithm women's actions is:

To the question that interests all women about whether there can be menstruation during the period of bearing a baby, experts give a unequivocal answer that these two concepts are absolutely opposite to each other. Even minor bleeding during pregnancy is a pathology that requires medical supervision and, possibly, emergency treatment.

It is for this reason that if you have any doubts about your condition, you should immediately visit a specialist. And this needs to be done as quickly as possible. After all, if a woman delays visiting the clinic, this can lead to disastrous events.

May indicate pregnancy. Another thing is that when regulation begins in the early stages, the patient does not know why it occurs and is worried. Any doctor can say with confidence that menstruation does not occur during the period when a woman is expecting replenishment.

During the cycle, the endometrium grows, which, in the absence of fertilization, is rejected along with mucus and blood. Therefore, it is impossible to carry a child and have a period; it is more likely to cause bleeding. In this article we will figure out whether menstruation can occur during pregnancy, and what consequences to expect.

Do you have periods during pregnancy?

Pregnancy and menstruation at the same time is physiologically impossible; to understand why, let’s remember the anatomy.

The uterus consists of 3 layers: the outer mucosa, the middle and the inner, each of them performs a specific function. The myometrium protects the fertilized egg and helps the baby get out during childbirth. The endometrium is the most variable layer, which grows in the first half of the cycle. Its goal is to preserve the fertilized egg until the placenta is formed.

Rejection of the uterine lining if conception does not occur. Mucus and blood come out, and then the whole process is repeated every month.

According to logic, if, while expecting a baby, the endometrium begins to be rejected, the fertilized egg will be released along with it, which will lead to a miscarriage. Therefore, menstruation does not occur during pregnancy; in rare cases, the reason for this is a bicornuate uterus, where the fetus develops in one part, and the cycle continues in the other. So, in the second part the endometrium accumulates, which is excreted in the form of menstruation.

Regulations at the beginning of pregnancy may occur due to late ovulation. That is, conception occurred in the previous cycle, but the fertilized egg has not yet reached the site of attachment. Therefore, doctors always count the period from the day of the last menstruation. If a woman has suspicions about an “interesting situation”, but her periods do not disappear, she should immediately contact a gynecologist. The norm is considered to be a small amount of blood discharge in the early stages of pregnancy, 10-15 days after conception.

Another reason for menstruation during pregnancy is considered to be hormonal imbalance, that is, excess progesterone or low amounts of estrogen. Usually the phenomenon does not threaten the child’s life if it does not cross certain boundaries. When the situation is complex and hormonal imbalance occurs due to any pathologies, you need to consult a doctor. Usually, this problem is easily eliminated by taking medications containing hormones, but you cannot prescribe them yourself.

What are they like

At the very beginning of pregnancy, you may notice unusual secretion from the vagina mixed with blood. The phenomenon is often dangerous, as it is bleeding. This happens due to disturbances in the reproductive system; most often, an ectopic or frozen pregnancy is diagnosed, as well as a threat of miscarriage. , dark-colored false periods and nagging pain in the lower abdomen are often provoked by the threat of miscarriage. The problem arises due to immunity disorders, when the body mistakes the unborn baby for a foreign body and tries to get rid of it.

A frozen pregnancy often does not manifest itself in any way, but dark, scanty periods, acute pain in the abdomen and softening of the mammary glands may appear. Fetal freezing occurs due to congenital anomalies, genetic diseases or increased uterine tone.

With an ectopic pregnancy, dark, slight discharge and pain appear in the area where the fetus was located. they talk about the spontaneous detachment of the fertilized egg during ectopic fertilization.


All these conditions are very dangerous for the patient’s life; one cannot tolerate it and wait until it gets even worse. Menstruation during pregnancy is dangerous, but there are situations when a woman confuses them with normal discharge. For example, damage to blood vessels in the vagina is often accompanied by bloody smears. Also, after a gynecological examination, discharge containing blood often appears. A similar thing is observed with two eggs in one. This happens if you take drugs that stimulate ovulation.

Not always both eggs are fertilized, so the “extra” one is excreted and menstruation occurs during pregnancy. Usually the discharge is not intense and is accompanied by the usual discharge. You need to be very careful about signs such as weakness, headache, fever, nausea, vomiting, dizziness, and increased heart rate. With such symptoms, consultation with a doctor is necessary, and in some cases, urgent hospitalization. Only a doctor knows, so any deviations require increased attention.

Why can menstruation occur?

The diagnosis is made based on the nature of the discharge during pregnancy; it can be serious or minor. In the early stages, menstruation may occur in the form of bleeding due to detachment of the placenta, which nourishes and supplies the fetus with oxygen. If the detachment is not significant, the body will most likely cope with this problem by increasing the amount of progesterone. At the same time, scanty secretion of a spotting nature is observed; there should be no other signs of disturbance.

In difficult situations there may be copious discharge accompanied by pain. With such symptoms, a visit to the gynecologist is inevitable; the patient should be completely at rest and observe bed rest.

If you ignore these rules, the question will be about saving the baby’s life. Miscarriage is caused by various reasons: neoplasms on the myometrium (muscular layer of the uterus), endometriosis, etc. If the fetus is attached to the affected area, it develops oxygen starvation which leads to death.

Go when the fertilized egg does not reach the uterus, and is localized in fallopian tubes. Over time, the embryo grows, causing rupture and internal bleeding. Other reasons for menstruation while expecting a baby include:

  1. Long-term use of hormonal drugs.
  2. Fertilization under regulation.
  3. Lack of progesterone.
  4. Death of the embryo in one of the trimesters.
  5. Genetic disorders.


The union of sperm and egg is also possible during menstruation. Due to hormonal imbalances, ovulation occurs before the regula, when the embryo is still in the fallopian tubes, and the uterine mucosa begins to be rejected.

This pregnancy will be characterized by unusual symptoms such as:

  • Early menstruation not on schedule;
  • Reduced duration;
  • Poor discharge;
  • to darker or lighter.

In any case, only a doctor can determine the exact cause of the bleeding, so you should not delay the visit.

In the later stages, some patients notice that after sexual intercourse, instead of the usual discharge, a bloody smear appears. It is caused by rubbing the sensitive cervix. This problem can be easily solved; it is enough to avoid sex before the birth itself, and for some time after it.

How to distinguish from ordinary

Rejection of the inner layer of the uterus, into which the fertilized egg is attached, can provoke the death of the embryo. It is for this reason that doctors call any blood secretion during pregnancy a bleeding. It is not always dangerous for the baby and expectant mother, but it is important to monitor your feelings. If the changes in the first month are caused by hormonal changes, the patient feels fine, there are no unpleasant sensations or discomfort, most likely the pregnancy and childbirth will go well.

Bleeding should be treated carefully, especially if the discharge is watery and dark in color, as these symptoms indicate a threat of miscarriage, inflammation or ectopic pregnancy.

Menstruation in an “interesting situation” differs from normal regular periods in the following phenomena:

  1. Absence of symptoms of early menstruation and swelling of the breasts, which does not disappear after its end.
  2. Too scanty, or, on the contrary, abundant secretion.
  3. Change .

All these symptoms can be accompanied by severe pain and deterioration in well-being. In order not to harm yourself and your baby, you need to go to the clinic in time to identify the cause of pregnancy regulation.

How they can be dangerous and when they are not dangerous


If during the period of bearing a child, a woman needs to be wary. According to statistics, secretion comparable to normal menstruation is dangerous; it threatens the health of the mother and child. Especially if the symptoms are complemented by cramping pain. Scanty discharge is usually practically harmless, but you should not refuse to consult a gynecologist. There are cases when a patient has periods after conception and accompanies her until the birth itself.

The child is born absolutely healthy, but it’s not worth the risk. At the beginning of pregnancy, single regulations are acceptable; during this period, a woman needs to monitor her feelings and the nature of the discharge. They should not go long and not disturb the expectant mother. As soon as your health worsens, it is better to call an ambulance. If there is a threat of miscarriage, the child can be saved by taking hormonal medications, as well as by curing the diseases that caused the abnormalities.
