Hello ladies, I was hoping to get some advice. Okay, I have been on the Mirena for about two years now. I have never had a problem with it until now. I get a extremely light periods every couple months or whenever it feels like it's a good day to pop up lol, and since I'm sexually active that's a little scary. I have also almost completely lost my sex drive, and sometimes my moods are everywhere. I have talked to my OB about it and he said it was almost completely normal.
