My experience has gone like this: I'm a big girl anyway but i have gained 40 ibs. since getting the Mirena in March 2007. The first 6 weeks i thought i would lose my mind. I bled the entire time more than when i had given birth! I saw my doctor and asked to have it removed he gave me meds to slow/stop the flow. I haven't had a "real" period since. I just spot every month. Right now I feel like im 8 months pregnant! Im totally exhausted all the time which isn't fun when you're trying to keep up with a 19 month old. I just had a brain storm about the weight gain and wondered if it could be connected. I think i finally found out why i haven't lost a single pound even though i go to the gym 3-4 days er week and have really watched what i eat and after a year of this i haven't lost anything. So like everyone else i will be calling first thing Monday to get a appt to have it removed.
