birth control
"WARNING TO THOSE WITH SEVERE CRAMPS: I had this in for 1.25 years. I gained 25lbs, had horrible mood swings, irregular bleeding but didn't get pregnant. The worst part was the severe cramping the 2 weeks before I had a period. I had to go to the ER because I thought something was wrong with me kind of pain. You know, shaking, sweating, can't cry or talk because it's so intense kind of pain. Labor pains level. I had it removed only to learn that the odds of the pain lessening are pretty slim. If you are experiencing this pain take the thing out!! You may get lucky and have a chance for it to subside."
