"i got kyleena inserted last week and just like everybody says it was painful but only for about 30 seconds it feels like a very strong period cramp nothing too bad. i also got it inserted on the 3rd day of my period (my periods usually last 5 days) and the iud ended my period early actually the same exact day. i didn&#039;t have any spotting until 4 days later and minimal cramping nothing to bad. the first day was the most most uncomfortable day but after that i felt fine. so far i definitely recommend it, this is my first type of birth control and i just didn&#039;t want to take a pill everyday because i know i would forget about it and the iud is a lot more effective. i will update my experience but it&#039;s not as scary as it seems like it would be."
