birth control
"I've had the Mirena for exactly 4 yrs. It has been the best thing ever. I have used pills, Nuvaring, the patch in the past, but all those things gave me bad side effects. I had no pain during insertion and cramped very slightly.  Although I should mention I am one of those women who rarely gets cramps and I had normal periods.  My periods practically disappeared and I didn't have significant weight gain.  I am back to my pre-baby weight and absolutely no side effects in these 4 years. I will be getting another Mirena."
