Placenta previa means the placenta is positioned low in the uterus, partially or completely covering the cervix. It is often detected at the routine scan around week 18–20. As the uterus grows, many placentas move upward naturally, but if it remains low later in pregnancy, additional monitoring is needed.

The most common symptom is painless bleeding in the third trimester. This can be frightening, but it does not always indicate danger. Ultrasound checks track the placenta’s position, and you may be advised to avoid vaginal intercourse or heavy lifting if bleeding recurs.

If the placenta covers the cervix at the end of pregnancy, a planned caesarean birth is recommended, as the placenta blocks the baby’s exit. If it is close but not covering, the plan is made individually.

With proper planning and monitoring, births with placenta previa are usually safe.
