I used to have the worst periods imaginable. Seriously, on my graduation day in high school I was in my bed, curled into a ball in tears because I couldn't move because the pain was so bad and my period was so heavy. Then I went on The Pill and it was ammmmmaaaazzziiinnnggg. My periods are still a little heavy, and I get SOME cramps, but not nearly the same severity.

If you really want the pain to stop, go on The Pill.
