birth control
"I have had my Mirena for 3.5 years now, and I think it's wonderful. I got it when I was 18 years old - I am not a candidate for most other forms of birth control because of my migraine headaches, so Mirena seemed like a good solution.  For insertion, my gynecologist numbed my cervix with an injection which helped buffer some of the pain. I experienced significant cramping for a few hours after it was put in, but a heat pad and a day of rest was enough to keep it very bearable. Since then my periods have become progressively lighter and shorter (now they only last for one day, and bleeding is so light that I rarely use pads or tampons), and I never get cramps. Bottom line = I love it. Talk to your gynecologist!"
