In most cases, sex during pregnancy is safe. In fact, with your health care provider's approval, sexual relations can continue until delivery.
However, fluctuating hormone levels and certain pregnancy symptoms such as nausea and tiredness can temporarily reduce a pregnant woman's libido (sex drive). In addition, visible changes in the woman's body may affect sexual desire. Always consult your health care provider concerning any questions you may have about sex during pregnancy.
Sexual intercourse may have to be avoided if the following symptoms occur:
Heavy vaginal bleeding
Pain during intercourse
Leaking of amniotic fluid
Contractions after intercourse that do not resolve
Check with your health care provider if you experience any of these symptoms.
