bleeding like a period during ovulation?

So I am ovulating now and have been having really bad cramps ever since my last period ended. I have also been nauseated too. Yesterday I started bleeding a little which I thought was normal since I usually spot during ovulation. But this morning I woke up and I am bleeding as if it is a full on period. Does anyone else have that happen? I am also still having really bad cramps. (Going to go to DR. Soon just want some advice-thanks)
I should add- I'm not on BC and know for sure I'm not pregnant
