With a normal pregnancy, you can keep having sex throughout your pregnancy—it won't hurt the baby. Your cervix is sealed by a thick plug of mucus that protects against infection, and the amniotic fluid and strong muscles of the uterus protect your baby. You may notice your baby is more active after you orgasm, but that is simply in response to your faster heart rate.1
Sometimes your doctor may advise you not to have intercourse if you have certain problems in your pregnancy; for example, if you or your partner has an STI (sexually transmitted infection) or if you have vaginal bleeding, a dilated cervix or placenta praevia (after you are 20 weeks pregnant, if your placenta is found to be attached to the lower part of your uterus, near your cervix, it is called placenta praevia).
