I've had Mirena for nearly two and a half years now. About 6 weeks after I got it in I had to take a pregnancy test because I was dizzy, nauseous, bloated, and had sore breasts. I was not pregnant. But I've had a repeat experience every few months since then. Sometimes I feel so sick and tired that I can't do anything but lie on the sofa. After I stopped nursing I got bad pregnancy symptoms and cramps so horrible I thought my IUD had punctured something. Currently I feel sick to my stomach, and I've been getting headaches, and I'm tired and terribly thirsty all the time. I've read about others who had the same problem. I've also had nearly continuous yeast infections and vaginal irritation since I got it in. My libido has dropped incredibly and I'm always kind of dry during sex. I had problems with depression before getting the Mirena, but now I have anxiety on top of that. At the two-year mark I started getting nasty under-the-skin acne under my chin, and I've gained ten pounds since then. Some of that might have been my own fault, but I currently eat healthily and exercise 1 to 1 1/2 hours most days, and it's taken weeks for me to stop gaining, and I know I'm losing way slower than is natural. I put up with it this long because I haven't gained huge amounts of weight or had really bad mood swings, and I'm afraid of what might happen with other types of birth control, but I am sick of being sick all the time. I'm getting this thing out!
