"i am 21 years old and don&#039;t have any children. i have had the mirena in for almost 2 years and at first i loved it, however i have had a few problems with it. i gained about 25 lbs, i am moody, not a very healthy appetite, no motivation for anything sometimes that included sex, but the past few months i have had nothing but stomach pain (scale of 1-10 about 8). it is very consistent and is there every day. i will be getting it taken out."
