hi everyone i am B. I had mirena put in in march of 07, At first i thought it was a great idea. But then i started gaining weight it was like over night. 20 lbs and i cant get rid of it. Then i always have migraines. I try taking Tylenol and nothing works. I look four months pregnant and im not, i cant have sex one i don't feel like it anymore and two it hurts. I always want to sleep., i have bad pain in my uterus that just wont go away. I have always been a nice person and i am sooo mean now its unreal.
