I had the mirena inserted in December of 07 and didn't realize that I was having some serious issues with this thing until about 4 months after insertion, my weight would not budge, I stayed at 220 for 4 months and I walked 90 minutes a day and am eating very healthy, some weeks I'd lose 3 pds and the following week would gain them right back, this happened for the entire 4 months, I didn't think anything of it until I did some online searching and found many woman complaining about weight gain with Mirena and other horrible side effects. I was having panic attacks and was always extremely emotional, I was also very bloated all the time, my husband looked at me one day and said you are exercising and eating healthy, why does your belly look so big? So, that was it, I knew it was the mirena. He also noticed my facial acne, which I never had in the 7 years he's been with me. I finally had the mirena removed on 4/14/08 and instantly found relief, I mean, when I say instantly, you may think I'm crazy, but it was immediate relief, I felt so much better in a matter of seconds. I did read somewhere that the mirena after it's inserted goes into your blood after 15 minutes so, not sure how true that is, but I believe it, after all I went through. I lost 1 pd in one day after the mirena was removed, and now 5/7/08 I've lost 9 pds so far. Not only was it a relief for the weight, I've also noticed a major change in my mood, I was always cranky and started to get nausea and felt bloated and just miserable all the time, my acne is clearing up, my hair also stopped falling out, which was another problem I had which I believe was a major side-effect, everyone said that it was because I just recently had a baby and it was normal, but after a while it was just falling all over the place so now I'm actually seeing the difference and my hair is starting to grow back in. I'm so glad I had it removed!!
