Vaginal intercourse can be continued as usual if your pregnancy is
uncomplicated. Discuss any concerns or questions with your health
professional.
Sex during the first
trimester will not cause any problems, such as a
miscarriage. The fetus will not be harmed by your partner's penis bumping the
uterus. The fetus floats in a cushion of
amniotic fluid.
Your interest in sex may change throughout your pregnancy. For
example, nausea and fatigue in the first trimester and physical discomfort from
your enlarged uterus in the last trimester may affect your desire for sexual
contact.
Sex during the second or third trimesters will not usually cause any
problems. Later in pregnancy, you may find sex most comfortable when you lie on
your side. Also, orgasm close to your delivery date may start uterine
contractions.
Your health professional will probably advise you to avoid sexual
intercourse if any of the following occur:
- The
placenta covers or partially covers your
cervix (placenta previa).
- Your "water"
(amniotic sac) has broken (ruptured
membranes).
- Contractions start earlier than 38 weeks (preterm
labor).
If you are infected with a
sexually transmitted disease (STD) during pregnancy,
it can cause serious problems for you and the fetus. If you are or may be
pregnant and are considering having sexual intercourse with a new partner or a
partner who may be infected with an STD, use condoms to protect yourself and
your baby.
