What causes ovulation pain?

Cyst rupture. The ovarian cyst actually ruptures to release the egg. The inherent damage to the ovarian capsule could be the source of the pain. The amount of pain varies from woman to woman and from cycle to cycle.
Fluid. When the egg leaves the ovary, there is sometimes a little fluid leaked into the abdomen, which causes some cramping. This generally goes away within a day or two.
