Levonorgestrel
"I am 20 years old and had Mirena put in 18 months ago after my son was 6 weeks and so far I like it but I do have some negative comments too. The insertion wasn't bad just had cramping after wards. My boyfriend feels it most of the time when we have sex. MY hair loss is pretty bad. I feel like I have 5 lbs I can't lose. I bled straight through the first month I had it in. Then didn't get my period or spotting for a whole year and now I get a regular period every month. Sometimes I do experience some cramping when I bend over a certain way and its sharp and very painful. But all in all I like that I don't have to take a birth control everyday and I don't have to worry about any more babies."
