After the birth of the child and the separation of the placenta, about 300 ml of blood flows out, and then the uterus begins to contract, stopping the bleeding. Since after the birth of the baby the uterus cavity is more like a wound surface, then it takes time to completely restore its mucous ( endometrium ).
Within the next 10 days, blood and blood clots can be released from the uterine cavity, and yellowish discharge (lochia) is possible throughout 1.5 months. In the norm of bloody discharge should be a little (a woman changes 1 gasket not more often than 1 time in 2 hours), if the discharge increases - possibly postpartum hemorrhage (especially if there are placental parts in the uterus and impossibility of its correct contraction).
Serous secretions should also not contain purulent impurities, if their color or odor changes, body temperature rises - these are possible signs of inflammation in the uterine cavity (endometritis) and should consult a doctor. That's why 1.5 months a woman is not recommended to have sex after childbirth because of the possibility to bring the infection until the uterine mucosa has recovered.
Restoration of monthly after birth
If the postpartum period is without specificities, and the woman does not breast-feed, then approximately 56 days after the birth the uterus cavity is restored, and 10-12 weeks after the birth, the woman has the first menstrual period. They may be different from those that were before the birth (by intensity and duration). 2-3 months irregular monthly periods are possible, and then gradually the cycle of a woman comes back to normal.
Absence of menstrual after birth: causes
First of all, the absence of monthly after birth can be caused by lactational amenorrhea. The hormone prolactin , which is produced in lactating women, not only stimulates the production of milk, but also inhibits ovulation, without which the monthly does not occur until the mother feeds the baby. Prolactin also protects a woman from becoming pregnant if she feeds the baby every 3 hours with an overnight break of no more than 6 hours. If a woman regularly breastfeed a child, then after childbirth there is no monthly one or more (up to 14 months), but this is rare.
Usually a woman can not exactly stick to such a schedule, and with the introduction of lures, breaks between feedings can increase. Even a small malfunction is enough to cause ovulation, so if there is not a long period of time after birth - do not relax: the next important reason for the absence of monthly births after birth can be a rapid onset of a second pregnancy, especially in a still not completely regulated cycle.
If the menstruation were at least once gone (and they can recover at any time even in nursing mothers), then no prolactin could slow them down, and pregnancy. And, if there has been a delay in the second month after childbirth, and even small symptoms of toxemia, it is better to do a pregnancy test.
Another reason, because of which there is no monthly after delivery, is the inflammatory processes of the ovaries that cause hormonal disorders in the body. Of the possible reasons worth mentioning are tumors of the uterus and ovaries.
Another disease that causes disruption of the menstrual cycle after birth is endometriosis, which especially often appears after surgical interventions on the uterus (caesarean section), after childbirth with a lot of ruptures and traumatization of the birth canal.
To say when exactly should be restored
Pregnancy before this time leads to the exhaustion of the mother and the insufficient amount of nutrients necessary for the next fetus. And if a woman does not feed the baby, and there are no monthly ones more than 2-3 months after the birth, then you should consult a gynecologist.
