There is no scientific basis for this. Everyone’s body takes a different amount of time to recover, and whether or not you are breastfeeding can also affect the time it takes to recover from your period. Early menstruation does not mean weakness. Births include vaginal births as well as cesarean births, and whether or not you breastfeed after delivery directly affects the onset of menstruation. The recovery of menstruation is different for each woman, and there is no fixed time at all. Most of those who are not breastfeeding will have their periods early, some will have their periods more than a month after delivery, while breastfeeding women will have their periods and normal recovery of ovulation a little later, some will have their periods only after weaning. The recovery of menstruation is not necessarily linked to physical weakness, and breastfeeding is currently advocated, not only for the recovery of the uterus after childbirth, to help the elimination of malodorous fluid to promote uterine contraction, but also for the strengthening of the baby’s immune system. After the birth must pay attention to good contraception, especially for women who had a cesarean section, even if no menstruation does not mean no recovery of ovulation, must be strict contraception for two years, otherwise scar uterus pregnancy is likely to occur after the uterus rupture. As long as the 42-day postpartum review is not a problem, normal menstruation does not lead to physical weakness, pay attention to strengthening nutrition.
