You should not have sex until you have recovered well for at least 42 days after giving birth. Some women may have to wait until 8 weeks or more after delivery to have sex due to slower recovery. The puerperium usually lasts 6 to 8 weeks, or 42 to 56 days. Most women are able to return to normal, including the vagina, cervix and pelvis, by 6 weeks after delivery. However, a few women recover more slowly, especially after cesarean section, and some need 8 weeks to return to normal. Early sexual intercourse can easily lead to the occurrence of infections. After all, the genitals have not completely recovered during the puerperium, and the immune system is low, so care must be taken to protect women’s health.
