"this review is about the insertion only. i had mine placed today so i can&#039;t review for effectiveness yet. i have never had kids. at the insertion, there was an uncomfortable pinch that hurt maybe a 4 or 5 on a scale of 1 to 10, but it only lasted a few seconds. the whole procedure took maybe 5 minutes. i took two tylenol before. i was not on my period because it has been irregular. i have had almost no bleeding from it. i was able to go into work afterward and work a full day. some slight stomach cramps for the first couple of hours, but walking helped and it was completely manageable. the only disadvantage i foresee is it can make period bleeding unpredictable for a while. don&#039;t let the pain reviews sway you. it really was not that bad."
