Miscarriage is the most common cause for early pregnancy bleeding, with ectopic pregnancy being an important second differential to be considered. As such any women presenting for the first time with vaginal bleeding >6 weeks gestation; vaginal bleeding with associated pain or ectopic risk factors at any gestation; or vaginal bleeding at an uncertain gestation should be assessed, ideally through local EPAS units.
This assessment should include an ultrasound scan to assess the location and viability of the pregnancy. If a miscarriage, ectopic or molar pregnancy is diagnosed on ultrasound scan these should be managed accordingly.
Women in whom a viable intrauterine pregnancy, with a fetal heartbeat, is confirmed should be advised that their risk of miscarriage falls to around 10% once the heartbeat has been detected. They should therefore be reassured and discharged, with advice to contact a midwife to book their pregnancy. If the bleeding continues beyond 14 days, or restarts after stopping, women should be advised to re-contact EPAS for further assessment.
