Q. A 27-year-old woman comes to the gynecologist for infertility. She says that she has been married for 3 years and trying to conceive for the past year but without success. Her menstrual cycles are irregular since her marriage and she is taking herbal medicine to get regular periods. She is not on any other medications. Her last menstrual period was 2 months ago with a scanty flow. Her temperature is 98.6°F (37°C), pulse is 90/min, blood pressure is 110/80 mmHg, and respirations are 14/min. Physical examination is unremarkable. Her lab investigations are shown below. A quantitative beta-hCG test is negative for pregnancy. What is the best next step in this patient’s management?
