Menstrual period is menstruation, and how long it takes for a woman to get her period after a cesarean section depends mainly on whether she is breastfeeding or not, which is usually around 6-10 weeks for non-breastfeeding mothers, and the time for breastfeeding mothers to get their period is not certain. If the mother is not breastfeeding after delivery, ovarian function will soon return to normal, and the normal menstrual cycle can be resumed 6-10 weeks after the cesarean section. If ovarian function recovers more slowly, delayed menstruation may also occur. If the mother breastfeeds after the cesarean section, some mothers have their period 8-12 weeks after the cesarean section, and some mothers have their period only after the breastfeeding period is over, which are all normal. Not having a period while breastfeeding is not the same as not ovulating, so it is important to use birth control to avoid pregnancy.
