You can have sex after pregnancy, but there are precautions to be taken. When having sex after pregnancy, it is best to choose the side or rear position to avoid excessive pressure on the pregnant mother’s abdomen. In addition, it is important to avoid sex during the first trimester and after the 36th week of pregnancy. Too frequent and intense sexual intercourse within the first 3 months of pregnancy may lead to miscarriage; after 36 weeks of pregnancy, intense sexual intercourse may lead to premature rupture of the fetal membranes and even placental abruption, which may endanger the baby’s life. Relatively speaking, the middle of pregnancy is a relatively safe stage. You should also avoid oral and anal sex during sex, as this will increase the risk of infection.
