I have had Mirena for about eight weeks, and my skin is worse than it ever was when I was a teenager and I also have felt that bubbly stomache thing that feels like a baby kicking. That is so weird! Also, I have been bleeding NON STOP! I have always had light periods with little to no side affects, but I have been crampy and have bled through onto so many skirts its not even funny. My mom told me to call my OBGYN and make sure that these were all normal side effects, but I thought I would see what I could find online first and stumbled across here. I'm glad I did.
