That's great information, but you missed 2 big ones. Memory loss and "brain fog" which is confusion to the point that you can't function in your daily life. These are listed in the Levonorgestrel side effects which is the progesterin in the Mirena. I was being tested for early dementia and alheimers for 6 months with the mirena. I found this site long ago, Mirena came out and now I'm fine. All the side effects are pretty significant when you are the one going through them, but when a contraceptive effects your brain, it's really scary.
