Q. A 33-year-old African American P2L2 woman visits her gynecologist for prolonged menstrual bleeding and abdominal discomfort for the past 4 months. She also complains of pain with intercourse. She does not have nausea, vomiting, or urinary or bowel disturbances. Her last menstrual period was 3 weeks ago and she had continuous bleeding for 10 days. She is sexually active with her new boyfriend for the past 1 year and occasionally uses condoms. She is not on any medication. She attained menarche at the age of 14 years. Her temperature is 98.6°F (37°C), pulse is 88/min, blood pressure is 110/70 mmHg, and respirations are 14/min. Physical exam shows a firm, irregular, non-tender, and mobile mass arising from the pelvis, corresponding in size to a pregnant uterus of 20 weeks gestation. What is the best next step in her management?
