"i realize the insertion experience is different for everyone but let me tell you, i think bikini waxes are three times as painful as a skyla insertion. it was nothing more than a period cramp sensation followed by a sharp pinch - all of lasting around 5-8 seconds. the worst part were the cramps that followed afterwards for a day but nothing a heating pad and some advil couldn&#039;t resolve. i am now on my second day and the cramps have subsided almost completely. i just wanted to write this review because there are so many horror stories out there and i believe those are the exceptions, not the norm, for the skyla iud insertion process. overall, i am very pleased so far!"
