"i am very happy with my mirena, besides the horrible acne.  i was on birth control pills to help take care of it.  every time my body thinks i am going to get my period, i break out pretty bad. insertion of the mirena was very, very painful. i would highly suggest asking for something for the pain if you have not had kids, get bad cramps anyway and are planning on getting this placed.  i was so sore for the first few weeks.  every once in while i will get random cramps on the one side where i always got really, really bad cramps.  but they are so minimal in comparison.  was good choice!"
