I totally agree that evey woman's body will react differently to Mirena. I THOUGHT this was the BEST thing that was on the market until I began to document my random and unexplained problems. So I caution you to please notice the change in your mood swings.. that's how it started with me. I brushed it off as having a bad day, but that day would turn into two days a week and then weeks at a time. I was a mad woman and could not explain it until I found one of these site and two weeks after I had it removed, I began to be myself again.
