This is my second round with the Mirena IUD. I got it back in 2010 after my daughter and had it for four years . I took it at in year four because of the smell. I started getting the thick white discharge right away around my period starting but the smell didn't come until year four. It's not a fishy smell but a rotten one. So I removed it. I had about two yeast infections in that four year span. Then I started pill Bc for about a year then got the Mirena IUD again . Now I'm on year two and the smell is back. It's very embarrassing as my bf has noticed it so i feel like other people may. I have an appointment with my gyn to check for infections. I don't want to remove it but I hate this smell .
