E.V.
I had the Mirena twice the past 4 years. The first time I had a few problems because it wasn't inserted correctly. It actually started coming out. The second doctor reinserted a new one and I had it in for over a year. I never had problems with heavy bleeding. My period stopped all together. The only negative side effects I had were hormonal. I took it out because my husband and I wanted another child and 4 or 5 months later we were successful. It's been a year since I had the last baby and I'm actually thinking about re-inserting another one.
