Is it safe to have sexual intercourse during pregnancy, and when can sexual activity resume after pregnancy?

　　If physical condition permits, sexual intercourse is generally acceptable during pregnancy, particularly during the second trimester (4 to 6 months of pregnancy). However, sexual activity is typically not recommended during the first and third trimesters.

　　For most healthy pregnant women without specific complications, sexual intercourse during pregnancy is usually safe. Particularly after the first trimester, the embryo has implanted stably, and sexual activity generally does not harm the fetus. If prenatal checkups show normal progress and the physician has not advised against sexual activity, couples can decide whether to engage in intercourse based on mutual comfort and preference.

　　Sexual activity should be minimized or avoided during the first and third trimesters. In early pregnancy, the fetal condition is still unstable, and intercourse may increase the risk of miscarriage. In late pregnancy, the physical burden on the pregnant woman is greater and the uterus becomes more sensitive; sexual intercourse may trigger contractions and lead to premature labor. During the second trimester (4 to 6 months of pregnancy), appropriate sexual activity is generally acceptable. It is important to ensure gentle and slow movements to avoid any accidental injury.

　　Pregnant women are advised to make decisions based on their individual conditions and preferences, following medical advice. If any discomfort occurs, prompt medical attention is recommended.
