Levonorgestrel
"I had my mirena for 2.5 years before taking it out. I've gained about 20-25 lbs since I fist got it. The procedure was extemely painful and I was in pain for the rest of the evening after the insertion. I've experience mood swings, lack of energy, spotting after intercourse, lack of sex drive, no periods (good thing), and regardless of clean eating/exercising, I could not loose weight. Oh and really bad acne!!

Since I've gotten it out I feel a lot better and not as tired. My partner says I'm so different from when I used to be on birth control."
