After finding this site I'm convinced that my weight gain and acne aren't something that starts because I'm getting close to 30. My stomach was flat in June of this year and I weighed 116 lbs solid! I'm currently at 138 lbs and run 4 miles every other day! My skin is very oily as well and my mom mentioned maybe my makeup was getting old...nope not the problem. I'm calling my doc tomorrow and I'm going to keep a journal on my experience for the women with questions on this site. Deep down inside I know that Mirena is the cause of my problems.
