Natural birth with placenta previa

Placenta previa means the placenta lies low in the uterus and may reach or cover the cervix. As the cervix changes or opens, the placenta can bleed. The position may be reassessed as pregnancy progresses because the relationship between the placenta and cervix can change. A Growth Scan or other ultrasound assessment helps the maternity team understand placental position and the baby’s growth.

If the placenta still covers the cervix or is too close to it, planned vaginal birth is generally avoided and a Caesarean Section may be recommended. The decision depends on scan findings, bleeding history, pregnancy timing and your overall condition.

Keep every scan and maternity appointment so placental position can be reviewed. Ask whether you need to avoid sex, vaginal examinations or strenuous activity; the answer depends on your bleeding history and clinician’s advice. Keep your maternity unit’s contact details available and arrange a practical plan for urgent travel to hospital. Tell any healthcare professional that placenta previa has been identified before an examination.

Go to the maternity unit urgently for any vaginal bleeding, even if it is painless or stops, and contact emergency services for heavy bleeding, faintness, weakness, severe pain or difficulty breathing. Do not wait for a routine appointment. Reduced baby movements, contractions or suspected leaking fluid also need prompt maternity advice.

Ask: Where is the placenta in relation to the cervix? When will it be checked again? What activities or examinations should I avoid? What symptoms mean I need immediate hospital care? If a Caesarean Section is advised, when and where will it take place?
