There is no exact time definition for how long you can have intercourse after a normal birth, and the exact time will depend on the recovery of the mother. Under normal circumstances, you can have intercourse in about 42 days. The reason is that during pregnancy, as the fetus in the womb grows and develops, the uterine wall expands and becomes larger. It takes about 6 weeks for the uterus to return to its normal size after a normal delivery. At this time, it is recommended that the mother go back to the hospital for a review to clarify the vaginal wound, the discharge of malaria, uterine regeneration and other conditions, all normal that can have a sex life. However, if the body recovers slowly after delivery and there is still vaginal bleeding, it is necessary to delay the time of intercourse. The relevant research shows that if the woman does not fully recover after delivery, having sex too early at this time can cause vaginitis, endometritis and other gynecological diseases, which can bring great pain to the woman’s normal life later. In serious cases, it may lead to more serious gynecological diseases, such as endometrial cancer, cervical cancer and other malignant tumors, resulting in a lifetime of regret for women. To sum up, it is recommended not to have intercourse too early after normal delivery and wait until the indicators are completely normal and the body basically recovers before having intercourse. In addition, when having intercourse, pay attention to good contraceptive measures and gentle movements to avoid the recurrence of genital trauma. And pay attention to maintain perineal hygiene to avoid cross-infection.
