"i&#039;ve had kyleena for about 10 days, and i can&#039;t say enough good things! my insertion experience was much less painful than i expected (i&#039;m 30 y/o, no kids). i took 550 mg of naproxen an hour before insertion, and i only had two sharp cramps, both of which only lasted a few seconds. i had some moderate cramping that evening, and otherwise it&#039;s been great! i&#039;m expecting my first period with it in the next day or so, and i&#039;m having more cramping than usual, but i understand that&#039;s pretty normal for your first period with an iud. don&#039;t let nerves dissuade you from getting one!"
