"i am 21 years old and have a 3 year old daughter. i had mirena placed a month postpartum. it was great at first. i had the dizziness and cramping after placement but a few hours and it was gone. i had my last period in december of 08, which has been great but the negative effects out number the 2 good effects. (no periods and no unwanted pregnancy) i have had mirena for just over 3 years now and i feel like crap. i have bad mood swings, nausea, abdominal pains so severe sometimes i want to cry, headaches at least 3 times a week, weight gain, bloating (badly) and extreme tiredness. i didn&#039;t want to believe it is my mirena because it works so well, but the worse my symptoms get, the more difficult it is not to blame mirena. getting it removed!"
