Most of the pelvic fluid in women during ovulation is around 1cm, and there is no abdominal pain, bloating and other discomforts, the pelvic fluid during ovulation is physiologic and does not need any treatment. There are very few individuals whose pelvic fluid during ovulation can reach about 1.5cm, and if there are no other discomforts, abdominal pain or bloating, no treatment can be done. When ovulation occurs in the middle of menstruation, the mature follicle in the ovary discharges the egg, and the follicular fluid in the mature follicle is also discharged along with the egg and flows to the pelvis, so it accumulates at the bottom of the pelvis, resulting in the accumulation of fluid in the uterorectal depression, or pelvic effusion, which belongs to the physiological accumulation of fluid. At the time of ovulation, because there is a small rupture in the ovary, there are a few cases where there may be a small amount of bleeding from the small rupture in the ovary, and a small amount of bleeding may also accumulate in the pelvic floor along with the follicular fluid, forming pelvic effusion. In conclusion, pelvic fluid does not need to be treated if it is around 1-1.5cm and the woman has no abdominal pain or bloating.
