The woman who gave birth to a normal baby can usually have proper intercourse 42 days after delivery, while a caesarean section is recommended to have intercourse 3 months after the operation. If the uterus has returned to normal and there is no vaginal bleeding, and the lateral incision has returned to normal, you can have intercourse, but you should also pay attention to good contraceptive measures. In case of cesarean delivery, due to the bleeding during the operation and the impact of the post-operative incision, the recovery will be slower. Most of them will gradually recover after 3 months of adjustment, such as rest and nutrition, and can have intercourse properly 3 months after delivery; meanwhile, it is necessary to place the intrauterine device in time 6 months after cesarean delivery to avoid unwanted pregnancy. In short, women should do a good job of contraception when having intercourse after the month, and also pay attention to keeping the vulva clean and hygienic to reduce the occurrence of gynecological inflammation.
