Your baby is cushioned by a sac of fluid well beyond the cervix or neck of the womb. There is no medical evidence at all that sex during pregnancy can do any harm to the baby.
A loving physical relationship is important for your health and well-being during pregnancy, and intercourse and orgasm can actually help your body to prepare for labour.
It may be advisable not to have sex at certain stages of pregnancy if you already have a history of miscarriage, premature labour, or if you have a low-lying placenta. If any of these situations apply to you, it's a good idea to consult with your doctor or midwife.
It's possible that you may notice mild contractions during and after sex, but if your body is not ready, these will not be powerful enough to start labour. If your body is ready, sex can actually help to start labour. Prostaglandins are contained in semen and these substances can help to soften the cervix. In addition, hormones released by nipple stimulation encourage the womb to contract.
Believe it or not, many couples find that pregnancy improves their sex life! It will certainly give you plenty of opportunities to find new ways of making love, by trying out different positions to find one that's the most comfortable for you as the 'bump' gets bigger.
