The short answer is, yes! During a "normal," low-risk pregnancy it is safe to have sex all the way up until labor. Many women experience fluctuating levels of desire, but if you and your partner are both in the mood for making love this Valentine's Day, having a baby on the way doesn't have to put an end to the fun.
What is a "normal" pregnancy?
Normal can be a very relative term, but in this case, women who have low to no apparent risk for miscarriage or pre-term labor can safely have intercourse. Even under these conditions, some physicians recommend avoiding sex in the last week or two before the due date. If you are unsure, speak with your medical care provider to determine if sex during pregnancy is advisable for you. You don't have to worry about disturbing the baby because the amniotic sac and the mucous plug that seals the cervix will keep your little one protected.
Are there any necessary precautions?
If you are considering having sex with a new partner outside of a monogamous relationship or with a partner with a history of STDs during your pregnancy, you should always use a latex condom or consider abstaining from intercourse. While oral sex with a trusted partner is safe, your partner should never blow air into the area because there is a chance it could cause a life-threatening embolism.
What will feel comfortable?
As gestation progresses, certain positions will be difficult to nearly impossible. Try to experiment with positions that remove any weight or pressure from your abdomen. Some women don't feel comfortable with their usual routine and prefer other intimate activities. Speak candidly with your partner to determine what works for both of you.
