Does anyone know what could cause someone to bleed while exercising (while not on their period)? I play soccer once a week and when I am not on my period during the game I get tremendous cramps, go to the bathroom and discover blood. It has happened to me about 5 times in a row and my doc is not sure what it is. I had an ultra sound to make sure i did not have any tumors or anything. I am very confused and wondering if anyone else has had this happen to them?
Thank you!

Hi Tulip,
I just starting doing the YBB (yoga booty ballet) series and I had my period last week and for some reason last nite after I finished my work out I starting bleeding to, I didn't know what it was from my workout either I felt great with the workout. However I dont think Its from the workout I think it may have something to do with my birth control.
