A 25-year-old female is admitted to the hospital with sharp pain in the left lower quadrant. Patient history reveals that her last menstrual period was 10 days ago. Transvaginal ultrasound reveals a ruptured cyst on the left ovary. The sonogram also reveals approximately 100 ml of fluid in the pelvis, which is presumed to represent cyst contents and bleeding from the rupture site.

Where is this fluid most likely located in this condition?
