I had Mirena placed 2 months ago. After experiencing all of the symptoms you have all talked about, I went in and demanded it be removed, despite my physicians resistance. She said that all of my symptoms sounded like a thyroid problem. I got my TSH tested, at the same time Mirena was removed. Just today got a call from my Dr. and my thyroid level is through the roof!!! Normal range is up to 4.0 My thyroid level is 131!!!!! I 100% believe that Mirena directly impacted this result, as the symptoms did not start until Mirena was placed. OMG!! 131!! I HIGHLY do not recommend Mirena....
