I'm starting to get nervous that I have endometriosis. I started having super heavy periods over the summer and was switched to a different birth control which helped a little. Well now I am on cycle 4 of being off birth control.

I started this morning and I am in so much pain , my insides feel like they want to explode, I am bleeding through tampons every hour and it is crazy heavy , looks like someone has been murdered when I go to the bathroom.

I do plan on calling the doctor on Monday, but what were your first signs that you had it?
