"i have been on skyla since october 23, 2014. it was an awful day of cramps the day i got it put in. and i am used to cramps, but those cramps were awful. my period had just ended but it started back up again once i got it inserted. my period seemed to last longer once i got the iud but only a couple days. and that only seemed to last for a few months. they&#039;re regular now but the god awful cramps continue. i&#039;m having my gynocolegist check it on and had to set up a sonogram. pain is never normal with an iud. also i gained about 10 lbs. my lifestyle changes right before i got on it, but it doesn&#039;t seem to matter what i do, the weight stays. but i am not pregnant and other then cramps and weight it&#039;s been awesome."
