"i read a lot of reviews about iud&#039;s... skyla in particular... and basically i  let them all really psyche me out. so many people said insertion was ridiculously painful and that cramping lasted for days afterwards. my experience was nothing like that. i only had my skyla inserted yesterday so i can&#039;t speak for the long term but i can say the most painful thing about my appointment was the almost 2 hour wait. insertion took only a few minutes and while it was very uncomfortable pain was minimal. it really just felt like period cramps. i took no pain meds beforehand aeveryone has different pain thresholds and i could imagine it being different for women who have never had children ( i have 2 both c-sections) don&#039;t let the reviews scare you"
