"i got the mirena 6 months ago and had non-stop problems from the start. while the insertion went smoothly, i had terrible cramps for the next month. my periods got much worse (i never had heavy bleeding or cramps during my period). after one particularly bad cramping episode, i went to my doctor who, after a sonogram, found that the mirena had worked its way into the lower part of my uterus (it seemed like my body was rejecting it). i also developed a 4cm ovarian cyst which is a listed side effect of the mirena. i had the iud taken out last week and i feel back to my normal self. i am not saying that mirena isn&#039;t a good option, as i know many people that love it. it was definitely not right for me."
