All I know is that I never had visited an online health forum in my entire life until my health fell apart while I had the Mirena in. I am slowly getting better now that the Mirena is out. My Dr. also said the Mirena couldn't do this. Just about every one on this forum had a Dr. who said the Mirena could not to do this. But they are obviously wrong (the Drs.). Just keep reading, and you will start to see the truth.
