"i have had the mirena for about two weeks. previously i would get cramps so bad from my period i would be bed ridden. i talk to my gyn and she suggested this. i can say that i still have cramping but it is not near as bad as what it was. and i am still spotting. the spotting is so irregular that having sex is kinda off the table right now. although my sex drive is crazy.  i am 19 years old, and its not to bad so far, but i am hoping it will get better, and that i can keep my normal weight."
