Menstruation delayed for one month during breastfeeding

We know that a woman's menstruation will temporarily stop after pregnancy and will not resume until after giving birth. But is it normal for menstruation to be delayed by one month during breastfeeding? The time it takes for breastfeeding women to resume menstruation varies. Some take three months, some take half a year, and some take a year. This is all normal. But it should be noted that ovulation is possible during lactation, so couples still need to use contraception.

Menstruation has not yet recovered during the lactation period, and it will not resume until about 42 days after delivery. Under normal circumstances, menstruation occurs once a month, unless there are special circumstances, such as irregular menstruation or pregnancy. However, many women also said that after giving birth, during the breastfeeding stage, menstruation will not come. Although this is a very normal phenomenon, for many people, the reasons are not understood, so many people are very puzzled. What are the reasons for delayed menstruation during breastfeeding?

The first thing a new mother does after giving birth is breastfeeding, and her body will also change accordingly. During lactation, as prolactin levels in the body increase, estrogen secretion in new mothers will be suppressed to a certain extent, and the ovaries will be insensitive to the stimulation of pituitary gonadotropin. So in general, there is no ovulation and no menstruation during breastfeeding. Theoretically, the morphology of endometrial tissue will change after delivery. Generally, ovarian function has basically recovered 33-42 days after giving birth, and ovulation can occur normally.

In addition, the corpus luteum can be observed after ovulation 6 weeks after delivery. Therefore, if the new mother does not breastfeed, menstruation usually comes within 6 to 8 weeks after delivery. Research data show that 40% of non-breastfeeding mothers resume ovulation 6 weeks after delivery; by 8-12 weeks after delivery, only about 35% of mothers have not resumed ovulation and menstruation. About 25% of breastfeeding mothers will resume ovulation and menstruation 12 weeks after delivery, and most breastfeeding mothers usually take until 18 weeks to fully resume ovulation function. New mothers need to pay special attention to the fact that the first menstrual-like vaginal bleeding after delivery is not menstruation.

In fact, by measuring the basal body temperature of the mother at this time, it can be found that 60% of them are anovulatory, which is strictly speaking anovulatory menstruation and cannot be regarded as real menstruation. The amount of bleeding and duration are much longer than normal menstruation, and the menstrual cycle is also irregular. Therefore, many mothers will experience irregular menstruation for a period of time after delivery.
