Additionally, physical changes may interfere with your desire for sex, including nausea, physical discomfort, fear of harming the baby and feeling less desirable because of your weight gain and appearance changes.
In the absence of conditions such as vaginal bleeding and ruptured membranes, sexual activity is safe during pregnancy. Don't worry about hurting the baby during sex; that won't happen because of the cushion provided by the fluid in the amniotic sac. Try different positions that don't put pressure on your abdomen. And if you're concerned that sexual activity might interfere with or cause a pregnancy complication, discuss the matter with your healthcare professional.
Your partner also may have a different sexual response to you during pregnancy. Some women report their partner draws closer to them during pregnancy, while others say their partners go through their own psychological changes and withdraw from the relationship. If your relationship becomes strained, your healthcare professional can refer you for counseling or other mental health services.
