I had my Mirena inserted in November 08. I immediately started experiencing sever mood swings and I was very angry and mean. I stayed depressed nearly the whole year to the point of feeling suicidal. I had nigh sweats and pains. I also gained almost 25 lbs during 1 year. My Mirena got "lost" in may of 09 and I could not feel the string, I had to have a sonogram to find it. That was really horrible. 4 weeks ago I started having a discharge and severe stabbing pains on the right side of my abdomen. I went to ER to have someone check me out but I left because teh wait was too long. The next morning I went to two doctors to try and locate the IUD and check for issues and they couldn't find the IUD or anything wrong with me. I knew I wasn't imagining the symptoms and I felt like I was going crazy. I finally got in to see my OB and she was able to locate and remove the IUD. The removal was extremely painful. She told me that the IUD was embedded into the back wall of my uterus. Its been exactly 1 week today since I had it removed and I feel 100% better. Almost all of my symptoms are gone. I would not recommend the Mirena to my worst enemy.
