Well, I have one side effect I haven't seen anyone mention. My breasts feel weird, like they did at the beginning of my pregnancy. I've been trying to figure out a way to explain the way it feels, and its a combination of when I had a yeast infection in my breast while breast feeding (not nearly as painful though) and the way they felt when I was in my first few weeks of pregnancy. I also have constant cramping, its not terrible, but constant. Then I've also had joint pain in my hips, I've woke up in the middle of the night with my hands asleep. And you can't even imagine the weight problems I've had. I weighed 180 two days before I had my twins, 160 when I came home from the hospital, 135 in January, and now I'm 175. If I gain 5 more lbs I'll weigh as much as I did 8 months pregnant with twins. I've tried dieting and I still keep gaining. Then my DH also says that I am not the same person. He was the reason I started looking into side effects because he told me one night that I've changed since I got the IUD and it is making me crazy. I thought he was crazy, that it was just because I had babies and more on my plate now, but then I thought that maybe he was right, that my moodiness and weird feelings combined could all be from the BC. Then I started researching. There are too many woman posting problems with the Mirena. I think it should be taken off the market (and they should pay for everyone to have it removed). If you go to Google and just search for Mirena IUD, don't include side effects or problems, just type in "Mirena IUD", you will get an official site, a couple of drug websites, and the others are sites for side effects. That should tell you something. There's even an support forum.
