MSFinals-1914

A 20-year-old woman was diagnosed with an early miscarriage 3 weeks ago through transvaginal ultrasound. She has no significant medical history and was G1P0. Expectant management was chosen as the course of action. However, she now presents with light vaginal bleeding that has persisted for 10 days. A recent urinary pregnancy test still shows positive results. She denies experiencing cramps, purulent vaginal discharges, fever, or muscle aches. What is the next appropriate step in managing her condition?
