Levonorgestrel
"I'm 31, married with 2 kids and was looking for a more permanent form of birth control. Overall I've been satisfied with the Mirena, I've had it almost 3yrs now. I didn't have too much discomfort with the insertion, just some mild cramping. The first 6 months my period was very irregular, a lot of spotting but not heavy and now it's more regular and has remained light which is nice, no cramping. My only compliant would be an increase in acne, that's really been my only side effect."
