abnormal uterine bleeding
"28yo and never been pregnant. I used ParaGuard IUD for 7 years with NO issue. A year ago my periods got heavy and 3-4 weeks long. Gyne didn't think that the IUD was the cause. We decided February this year to try the Mirena to lighten my periods. It worked! However, I did have extreme breast tenderness, moodswings, etc. About 3 months later I experienced the worst cramping I'd had in over 10-15 years and the Mirena was expelled. In June I had a new one put back in. A few days ago (this is August), I had unusual cramping and as of yesterday the second Mirena expelled. I am not pleased. I'll never use Mirena again. I will go back to using the copper one since there were no side-effects."
