You are covering an obstetrics clinic for your colleague, who left for vacation last week. A healthy 32-year-old primigravida at 13+4 weeks’ gestation called for an emergency appointment after experiencing two episodes of postcoital bleeding over the past week. She met your colleague last week at her first prenatal visit, which was unremarkable. Sonographic dating was appropriate for menstrual age, and first-trimester fetal anatomy was normal. You note that all routine prenatal serum laboratory investigations are normal with low-risk screening tests for fetal aneuploidy. Without a cervical smear in over two years, cytology was performed, and results are expected shortly.
