The short explanation
For most women with a healthy pregnancy, sex is safe throughout pregnancy and does not harm the baby. The baby is protected by the amniotic fluid, the strong muscles of the womb and the cervix, which is sealed with a mucus plug. Many families believe sex should be avoided, but medical evidence does not support this for normal pregnancies. Your doctor may advise avoiding sex in certain situations, such as unexplained vaginal bleeding, placenta praevia where the placenta is low, leaking fluid, a history of preterm labour, or a weak cervix. If you are unsure, ask your doctor at your next antenatal visit.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- As pregnancy progresses, some positions may become uncomfortable. Choosing comfortable positions helps.
- Desire can go up or down in pregnancy; both are normal.
- If either partner may have an STI, use condoms, as some infections can affect pregnancy.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether sex is safe in your pregnancy. Your doctor can advise based on your health and scans.

Take these with you. You can add any of them to an appointment card.
