I have been a crazed woman the last few months and thought it was all in my head. I got Mirena inserted in November 2008 and have had almost all of the symptoms the other women have posted. Some I did not even think could be related to the Mirena. I definitely have had weight gain, cramping, sore breasts, headaches, depression, mood swings, and LOTS of acne. I have also had eye twitches, abdominal pain, and pain in my legs. I have also been tired and never wake up refreshed any more. I have been exercising less as a result. These are the things I had no idea could be due to the mirena. What an eye opener. I called my doctor today and he suggested I keep a journal to keep track of how I felt and that I research the side effects. He also said he would take it out immediately if I so choose. I chose to do the former. But after reading and researching, I think I will call him tomorrow and make an appointment to remove it immediately. My husband and children will be forever grateful!
