"2 years ago i had it inserted. there was some intense cramping during the &quot;sound&quot; and the actual insertion, but it took less than five minutes, and there was no pain, but slight discomfort, for the rest of the day. i got my period a week early and it was much heavier than before (used to be light 6 days, changed to extremely heavy 5 days). my period has gotten less extreme over time, and now it is extremely heavy for 3 days. it took a few months to not feel it at all. occasionally (once every 6-9 months) sex is too rough and i get stabbing pain in uterus for a few days, but other than that i am able to tell my partner when it is too rough and i don&#039;t have any pain. partner felt it once in the 2  years i&#039;ve had it. 8/10 for the heavy periods"
