Placenta previa bleeding after intercourse: what to know

Placenta previa, also called a low-lying placenta, means the placenta is close to or covering the opening of the womb. The cervix becomes more sensitive during pregnancy, and contact or contractions can disturb nearby placental blood vessels. Bleeding may be bright red and may occur without pain, but its amount can change quickly.

A scan can show the placenta’s position and whether it has moved away from the cervix as the pregnancy progresses. The location and your bleeding history help the maternity team plan follow-up and birth.

Stop intercourse and contact your maternity unit for advice even if the bleeding settles. Do not insert anything into the vagina unless your clinician specifically advises it. Keep a note of when bleeding began, its colour and amount, pain, contractions, and your baby’s movements. Your team may arrange an examination or growth scan and give personalised activity guidance.

Call emergency services or go to urgent maternity care for heavy bleeding, clots, abdominal pain, regular tightenings, faintness, weakness, or reduced fetal movement. Do not drive yourself if you feel faint. Even light bleeding warrants prompt contact because placenta previa can bleed without warning.

Ask whether intercourse and pelvic examinations are currently safe, how the placenta’s position will be rechecked, which symptoms require hospital attendance, and how a caesarean section would be planned if the placenta remains over the cervix.
