Ovulation bleeding

Sooo, it seems for the past few months I've started bleeding very badly while I ovulate. It's ridiculous because it's similar to that of a heavy period for two-three days.
I've been to two GYN but they insist it's normal. This has never happened to me before and it brings awful cramps and I'm dead to the world when it happens.
Does anyone else have this problem? If so, what is it?
