"i&#039;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&#039;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&#039;m going to get it removed ... i can&#039;t stand the weight gain."
