Levonorgestrel
"I got the mirena 3 days ago and I've had nothing but pain ever since. It's not severe pain, but bad cramps that don't go away, even with advil. The insertion was SUPER painful and seemed to take forever, but that could have been because I had to get it done at a "teaching" clinic and the guy didn't know what he was doing. I'm 28, no kids. I like the idea of an IUD but I just don't know if it's for me."
