Think I have endometriosis

Nicki • Going to be 21 years old soon and ready for baby #1
I have not yet had it checked out by a dr but when I get my periods I have the worst cramps. Today I am my supposed to start for a few more days and I have SEVERE vaginal and stomach cramps. Not discharge or bleeding of any kid today. I have taken tests all bfn between yesterday and today. When I'm on my period I have HORRIBLE cramping the entire time where nothing helps it. Does that sound like endo
