"worst experience. insertion took way too long and was so painful. my doctor had to cauterize me with silver nitrate to stop the bleeding. i was nauseous and dizzy for half an hour after.  they did an ultrasound to be sure it was in place, it was. after a week with horrible cramping and bleeding i went back in for a recheck. another ultrasound showed it had rotated and was lodged in my uterus. removed and will never have this iud again. if i could give zero stars i would."
