What should you know?

Placenta previa means the placenta partly or completely covers the internal cervical opening. A low-lying placenta is nearby without necessarily covering it, and its relative position often changes as the uterus grows.

The classic symptom is painless bright bleeding later in pregnancy, although the diagnosis may be incidental. Ultrasound establishes placental location; unplanned digital vaginal examination can be dangerous when previa is suspected.

Common symptoms and signs

Painless bright-red bleeding in the second half of pregnancy
Incidental finding at a routine scan
Non-cephalic fetal presentation
Contractions or pain when another condition coexists

Diagnosis and the role of ultrasound

Transvaginal ultrasound is safe and most accurate for measuring the distance between the placental edge and internal cervical opening. Follow-up timing depends on the initial result and bleeding history.

Whether the placenta covers the opening
Exact placental-edge distance
Anterior or posterior location
Possible placenta accreta spectrum signs

Ultrasound findings must be interpreted together with symptoms, examination and, when needed, laboratory or other imaging results. An image alone should not be used for self-diagnosis or self-treatment.

Treatment and next steps

Care depends on bleeding, gestational age and final placental position. It may include repeat imaging, individualized activity advice, hospital observation and planned mode and timing of delivery.

Management is individual and depends on age, symptoms, imaging findings, other health conditions and pregnancy plans. Medication or a procedure should be selected with the appropriate clinician.

When is urgent care needed?

Any new bright bleeding during pregnancy
Bleeding with weakness, dizziness, contractions or pain
Reduced fetal movement
