Has anyone been diagnosed with Endometriosis? If so please please tell me what your symptoms were/are? On the first day of my period I’m nauseous constantly puking and pooping at the same time. My stomach hurts so bad and I can’t even stand it. I have to take Benadryl to knock me out and even when I wake up the pain is still there. The only thing that knocks off the pain for a little bit is Masturbation. Anyone have tips?
