Abdominal examination discloses mild lower quadrant tenderness that is greater on the left side; there is no guarding or rebound. Pelvic examination discloses a small amount of brown discharge in the vagina, mild cervical motion tenderness, and a closed cervical os. Results of laboratory studies are shown:
