I had the Mirena for almost 2 years and in those two years I've gained 40 pounds! I started getting acne on my face, I'm 25 and I've never had acne in my life! My family thinks I'm bipolar from my mood swings. I couldn't stand it anyone, so I made an appointment and got it removed today! I set up a appointment for the copper iud. I don't care about heavier periods, as long as I don't gain anymore weight,acne, and attitude!!
