Hello,
A certain amount of free fluid in the pelvis, behind the uterus, is normal at certain points in your cycle; after ovulation, a small amount of fluid released with the egg collects behind the uterus and is eventually reabsorbed by the body
A larger amount of fluid may indicate a ruptured ovarian cyst. Pain is usually present in this instance, but most often resolves on its own within a few days. Infection is another possibility
