I was put on the Pill for severe cramps during my period and the first two months were great I felt no pain whatsoever. The third month in the pill a week after my period had ended I had extreme abdomeninal pain that was so bad I had to skip classes ( I'm in college). After a few hours it went away. A week before my was supposed to start the pain came back and then I had a full period. The pain lasted for 5 days before I finally felt normal. I went to the gyno and she says I might have endometriosis so she changed my pill to see if that helps. My period has been over for a few days and suddenly my abdomen started hurting again. Has anyone else had something like this happen to them?
