Right now I can't sleep, bad cramps, bad lower back pain, cysts, acne mostly around my mouth (which I am usually really clear), headaches, stomach flutters, not to mention mood swings like heck!, more discharge then usual... for starts. I thought it was just something else or me going crazy... after reading all of your comments I am starting to think other wise. I have already been to the ER with horrible stomach pains and cramps, but all the tests came back just fine, just got a 2,000+ bill. I just wanted them to take it out, but they said it wasn't the mirena and it doesn't cause these kinds of things. I have had it almost 9 month... could it be the Mirena causing this?
