A woman at 32 weeks has painless bright red vaginal bleeding. What is the most likely diagnosis?

Answer and explanation

Correct answer: A. Placenta praevia

  1. Step 1: The picture of painless bright red vaginal bleeding fits Placenta praevia.
Answer
Placenta praevia.
Why not the others: 'Placental abruption': it gives painful dark bleeding with a rigid uterus. 'Vasa praevia': it gives bleeding with fetal bradycardia after membrane rupture. 'Cervical ectropion': it gives light postcoital bleeding.
