birth control
"I've had mirena for about four years.  I was the same weight for the total of 11 years. Since having it I have gained about 30 pounds.  It works good because you don't have to remember taking pills or putting in a ring. I was told that I would not gain weight. It made my periods lighter. I started to get acne. I get bad cramps and a headache before my period. I tried to stick it out but I'm going to get it removed ... I can't stand the weight gain."
