Patient-Friendly Summary of the ACR Appropriateness Criteria: First Trimester Vaginal Bleeding

First trimester vaginal bleeding occurs in 7% to 27% of pregnancies, with many causes that range from a normal pregnancy to an ectopic pregnancy (pregnancy outside the uterus). The main imaging test recommended is transvaginal ultrasound (US), which when combined with blood tests and the mother ’s signs and symptoms can identify the cause of bleeding.
