The purpose of this study is to determine fetal outcomes of women diagnosed with live intrauterine pregnancy after emergency department (ED) presentation for abdominopelvic pain or vaginal bleeding during the first trimester. ⋯ Fetal loss before 20 weeks occurs in 9.2% of patients with live intrauterine pregnancy diagnosed by ultrasonography. Vaginal bleeding carries a higher fetal loss rate of 13.8%. These data will assist the emergency physician in counseling women experiencing symptomatic first trimester pregnancy.
