In each individual case, this process passes individually, so it is impossible to say unambiguously, when after the birth, menstruation begins. Normally, the resumption of the menstrual cycle can occur in 2-3 months, and in 2-3 years. Nevertheless, it is possible to determine some tentative time frame for the recovery of the monthly after delivery.
Why after the birth is not monthly
Much depends on whether you are breastfeeding and, if feeding, in what mode. So, in most cases, absolute breastfeeding on demand is the most important reason for the absence of menstruation. And the whole thing is in the hormone prolactin, which activates the production of breast milk and suppresses the onset of ovulation. Physiologically, menstruation should not resume until breastfeeding ceases. And a few dozen years ago it was like this: women within 2-3 years after childbirth had a carefree in terms of monthly lives.
But under the influence of various factors today the cycle can be renewed at various times. However, the relationship with breastfeeding is still dominant: as soon as you have introduced a lure or weaned the baby from the breast - wait for menstruation in this or in 2-3 months. And if a woman for some reason does not put the baby to her breast, then most likely, the month will begin in her already a half to two months after childbirth. But these are only averaged indicators: there are cases of very early (already 3-4 weeks after delivery) and a record late (3-4 years after the birth) of the resumption of the menstrual cycle.
In the process of restoring the cycle, the state of health plays a role, full rest and adequate food, birth and postpartum complications requiring hormonal therapy, the psychological state of a woman. The onset of the first months after birth is not related to the way of delivery. Whether natural or artificial delivery, they practically do not influence the speed of hormonal restoration (although in some cases, after a cesarean section, menstruation may not be on time).
How many are monthly after birth
Separately it is worth mentioning lochia. These are spotting accompanying the healing of the uterus after placental rejection and having nothing to do with the months. Lochias begin immediately after childbirth and can last several weeks (normally not more than 6-8), gradually changing its character: from abundant red to meager, sugary-brown, smoothly turning into white and yellow discharge.
The real menstruation is only resumed after some time after delivery. Initially, they may differ irregularly, start earlier or with a delay, but after 2-3 cycles should be normalized.
Be prepared for the fact that the nature of the months after the birth can change, and in any of the parties. Many women note that the discharge becomes less painful and plentiful as before, but it also happens on the contrary. You should be alerted to menstruation, lasting too long and intensely. You should also consult a doctor if, 2-4 months after the complete cessation of breastfeeding, the men have not resumed or become regular, or if the allocation is very meager or, on the contrary, too abundant.
And do not forget about contraception. There is a misconception that while a woman is breastfeeding, pregnancy is not possible. In fact, ovulation can occur and against the background of the absence of menstruation. Many women just so become pregnant shortly after birth, which is not very desirable for the future child and the mother's body.
