Pabloh,
Have you had any testing or procedures? I am just asking because of going through YEARS of endometriosis and infertility beginning in my 20's. Anyway, before taking a pill I would find out the cause first. A long time ago my Reproductive Endocrinologist told me that yes, while menstrual cramps are painful, they shouldn't be so severe as mine were. Soooo...I probably had endometriosis in my teens...just didn't know it then. I would just get checked out and let the doc know what you are going through. Back in the day all I could do was to take Tylenol and was put on the "the pill" which did help. But never knew I had this other until I tried to get pregnant. Just a thought.
