Monthly in pregnant women - a myth or reality?
Before you understand the very nature of thisphenomenon, like the monthly during pregnancy, it must be said that it occurs in 10-20% of expectant mothers. What is the reason for this? With different studies of the nature of menstruation during pregnancy and different approaches. For example, if only mild and moderate bleeding were taken into account, then according to statistics, such phenomena were observed in every fifth pregnant woman. If only severe bleeding and moderate bleeding were taken into account, then the statistics showed the presence of such processes in every 10th pregnant woman. The different approach in accounting is explained by the fact that weak bleeding that occurs in future parturient women, besides, if they are extremely rare, are accepted by doctors as the norm. Such processes, as discussed above, are found in every 5th future mother and manifest during the first 3 months of pregnancy. And if the menstruation can cause panic and anxiety in the future childbirth, then an experienced doctor like this phenomenon can not outrage. At least until the time when no tests are done and no tests are taken from a pregnant woman. And the stories that the whole pregnancy went along with the monthly ones may turn out to be the most complete truth, but only in part. The fact is that such bleeding is not a sign or an accompanying element of menstruation, since the last phenomenon in its full sense can not occur in a pregnant woman. Then what is it? 
Physiology of menstruation
In order to understand the causedescribed processes, it is necessary to disassemble and determine what constitutes the process of menstruation. By menstruation is understood a part of the menstrual cycle in a woman, during which the uterus rejects the mucous membrane. Otherwise this layer is called endometrium. The phenomenon of rejection itself causes bleeding in a woman. Bleeding in a woman during menstruation is caused for the following reason. This mucosa, which covers the walls of the uterus, is permeated with a variety of blood vessels, which ensure its excellent blood supply. When the monthly cycle occurs, as well as other processes in the ovaries, the mucous membrane reacts extremely sensitively to them. Experts such sensitivity is associated directly with female hormones. So, it is established that when the follicle increases, it is accompanied by the release of estrogen. In turn, estrogen stimulates the process of increasing the inner lining of the uterus in size. During the period of ovulation, a yellow body forms, which replaces the follicle. This process is associated with a female hormone, like progesterone. This female hormone, progesterone, promotes the accumulation of useful substances in the mucous membrane (endometrium). Simultaneously with this accumulation, this hormone prepares this membrane for the adoption of a fertilized egg. But if the fertilization of the egg does not occur, after some time, counted in several weeks, the female organism stops the production of progesterone at the same time as the cessation of the work of the yellow body. As soon as the amount of this hormone decreases, the mucous membrane atrophies and stratifies. At the same time, blood vessels are denuded and their trauma occurs. As a result, a portion of the mucous membrane, its fragment, mucus and the blood of these exposed vessels form menstrual blood. Many women noticed that their menstrual blood is slightly different from ordinary blood. Now it is clear why. In the event that fertilization of the ovum takes place, the yellow body remains active. This activity continues throughout the first 3 months of pregnancy. So, during this period, the female body continues to produce hormone progesterone, ensuring the safety of pregnancy at this time. Since fertilization of the egg with the sperm occurs, the process of rejection of the endometrium does not occur. The mucous membrane is not rejected because of the process of pregnancy in a woman. If under such conditions a woman has a bleeding, then this is by no means a period in the strict sense of the word. It is about the possible rejection of the mucous membrane and, as an undesirable option, abortion. It is for this reason, if a woman is in a position and she has a period, you should immediately go to the doctor. To think in such a situation about the miraculous property of your body is not worth it. The reasons for joyful surprise are not perfect.
Causes of monthly onset of pregnancy
So, bleeding during pregnancy is notis a sign of menstruation or their manifestation. As indicated above, the cause of bleeding may be that the mucous membrane (endometrium) is being torn away and as a result of this process the pregnancy is interrupted. But this is not the only reason why the so-called monthly pregnancy can begin. 
When there is no cause for concern?
The reason for the uninvited, short-termbleeding in a pregnant woman may be due to the fact that a fertilized egg was correctly implanted through the uterine wall. As a result of such implantation, bleeding may occur, which is mistaken for a month. For the development of pregnancy, this isolation does not pose a threat, and because of its short duration, neobylnosti and painlessness, it does not deliver to the woman those troubles that she experiences during traditional critical days. For such a case, it should be noted that the discharge will manifest itself in the form of several blood droplets, which the expectant mother can notice on the laundry and which are extremely rare. If the allocation does not meet these criteria, then this is a different case and other reasons. Another reason for such periods are hormonal changes. The organism of the pregnant woman can give off bleeding in the periods in which there should be monthly if pregnancy was not. Such discharges are fairly mild, not accompanied by pains in the lower abdomen, in the absence of other problems do not pose a threat of miscarriage. The next reason for the appearance of secretions during pregnancy is associated with a low level of hormones, which are synthesized by the placenta. Such bleeding is possible first, early pregnancy and do not pose a threat to the fetus and to the woman. But in this, at first glance, non-dangerous case, you need to seek medical advice from a doctor. Drawing a conclusion, it is necessary to emphasize especially: as soon as the pregnant woman has noticed spotting reminding monthly, she should address immediately to the doctor. Regardless of the period of the fetus being born, the nature of such secretions should be explained by a specialist doctor, not a girlfriend, a mother or a midwife. The human body is complex enough to seek simple explanations for the complex processes taking place in it. All the exhortations of a close environment about the fact that bleeding during the gestation of the fetus - a phenomenon quite common, should not be taken into account by the future childbirth. It is possible that at this stage, such allocation is not an excuse for excitement, and there are women who, having such phenomena, safely nurtured the fetus and gave birth to healthy kids. But why hope for a successful outcome, if it is possible to obtain a conclusion, and if necessary, and help from a qualified specialist? Or is there a desire to risk your health and fetal health because of carelessness? This is a rhetorical question. 
Monthly in pregnant women - cause for concern
It was mentioned above that bleeding in pregnant womenwomen are, if not cause for concern, then certainly require immediate medical attention. It is very good if the future maternity leave is not an alarming symptom. But it is necessary to know that according to statistics, out of all miscarriages, the main part, up to 80%, falls on the first 3 months of pregnancy (on days when the woman had menstruation before she began to bear the fetus). In the environment of medical specialists on this issue it is considered that any allocation during this period is a serious sign that there is a threat of miscarriage. It is for this reason that doctors insist that with any discharge from pregnant women, they are urgently required to seek medical advice and to conduct an examination. It is possible to attribute such requirements of doctors to the phenomenon of reinsurance. Many faced with the fact that the prescribed treatment associated with staying at home or in a cast, release from active movements, somewhat with a margin. But this opinion is more subjective, because what the specialist sees, and the practice that he went through, is inaccessible to a stranger, who has in his head scrappy information from the textbook on anatomy for the 9th grade. Opinions of doctors can differ and between themselves. Above it was indicated that the monthly during pregnancy for various natural causes. If the hormonal background does not have time to rebuild the hormonal background, its changes are delayed in relation to those processes that occur inside its organism (it is a question of the appearance of the fetus), then it can quite observe the uninvolved discharge that does not cause painful sensations. But such manifestations are allowed in the first month of bearing the fetus and are considered quite acceptable. If these phenomena occur in the second month of bearing the fetus, then this is a rather alarming symptom. Anxious symptom is for the doctor to start a serious examination of the future mother. But if there are cases that allow monthly for pregnant women, is it necessary to go to a doctor without exception? There is such a need. Mistakenly calculating the blood discharge for a normal process that takes place inside due to some forgetfulness of the organism or an inadequate reaction of hormones, one can not overlook the development of undesirable phenomena. For example, such carelessness can cause that infectious diseases or inflammatory processes of internal genitalia are not noticed. The "pranks" of hormones can be harmless, do not harm the health of the fetus, nor his mother. And serious pathological hormonal changes can occur, for the prevention of which the doctor's help is needed. Bleeding may be a sign of internal trauma or evidence of stratification of the placenta. If there is a problem with the fetus being born (for example, the egg is peeling off) or other pathologies of its development, bleeding becomes one of the signs of this. Medical care in such cases is required urgently. 
Threatening hormonal changes
As mentioned above, during pregnancy,there is a violation of the allocation of a hormone such as progesterone, when the female body allocates it is not enough. As a consequence of its inadequate isolation, the uterus can tear off the fetus. If in time to recognize the cause of secretions in this case, the doctor prescribes medications that replace this hormone and prevent the appearance of the process of rejection of the fetus. Otherwise, when a drug effect on hormone action in a pregnant woman is required, she has an elevated level of male hormones. This phenomenon is called hyperandrogenism, as a result of which the fetal egg can exfoliate, which leads to an unavoidable miscarriage. One of the causes of hyperandrogenism is bleeding. The next case is that the fetus develops outside the uterine cavity. Otherwise, this phenomenon is called an ectopic pregnancy. Ectopic pregnancy can be detected only with the help of qualified medical care. But her signs that a woman needs to immediately consult a doctor are very severe pains, which are accompanied by heavy bleeding from the vagina. Subsequently, such allocation becomes more and more prolonged. In cases where a pregnant woman is diagnosed with fibroids or endometriosis, there is a high probability that the attachment of the fetus has failed. This means that the fetus will be poorly supplied with oxygen, with its development there will be serious problems and, as a result, the fetus will be lost. The primary signs of this process are the so-called monthly ones during pregnancy. Do not think that such allocation is possible only in the early stages of bearing the fetus. When the fetus lasts up to 7-8 months, the placenta can block the entrance to the cervix due to its low location. This phenomenon can be observed in those women who had previously interrupted pregnancy or gave birth by caesarean section. Bloody discharge in such women is evidence of placenta previa. If a woman carries 2 fetuses, then the maternal ones during pregnancy can testify that there is a rejection of one of the embryos due to different circumstances. Despite this, the second embryo can develop quite normally, without pathologies.
Correct behavior: what should I do?
As you can see, the description of the above processes,which can occur in the body of a pregnant woman, are very different. Their primary symptoms in the form of blood secretions can equally manifest as those who need to worry about their health and fetal health are not worth it, and those who need immediate medical attention. The most universal advice that should be given to all future mothers and which begs for itself is that if a woman in labor finds herself on a monthly basis, she should immediately call a doctor. This will prevent any unwanted processes that lead to a deterioration in the health of a pregnant woman and the termination of pregnancy. Strong to you health and happy motherhood!
