"insertion of skyla was simple, though a little crampy, but the doctor has to clamp your cervix so of course that&#039;s not going to be comfortable. i only bled for that day and 1 day after and the cramps subsided after the first day. i&#039;ve had skyla for about a month now and have had no problems with it. surprisingly my last period happened right on schedule. i was on the pill for 5 years prior to skyla and had never really had cramps due to that. now that i&#039;m not taking the pill my period cramps have been intense but i doubt it&#039;s due to the iud. other than the normal that-time-of-the-month cramps and bleeding, i&#039;ve had neither spotting or random cramping. i would definitely recommend skyla."
