Menstruation may occur 50 days after a cesarean section, but there will be individual variations. Cesarean section is a surgical procedure to terminate a pregnancy and is performed by a specialized physician. The return of menstruation after surgery and the timing of ovulation can be affected by breastfeeding. In general, women who are not breastfeeding usually return to menstruation about 6 to 10 weeks after the operation, and ovulation resumes about 10 weeks after the delivery, so menstruation may occur 50 days after the cesarean section, but there are individual variations. After cesarean section, you should also pay attention to appropriate activities to promote physical recovery and prevent thrombosis, increase protein-rich foods, keep the vulva clean and dry, pay attention to the healing of the abdominal incision, prohibit pot baths and sexual intercourse for 6 weeks. After 6 weeks of delivery, follow the doctor’s instructions to review the uterus and pelvic floor tissues to understand the recovery of the uterus and pelvic floor.
