"i had kyleena inserted today, just 8 hours ago. this was the first iud i&#039;ve ever had, and i have never been on other birth controls (other than condoms). i&#039;ve never given birth.  i never really had period cramping, so i knew going in that this could be painful. the lpn sounded my uterus, which brought on like 2 mild cramps. next she told me to take a deep breath in and cough. i panicked and asked &quot;when do i cough?&quot; and at that time she inserted the device. i had maybe 3 or 4 sharpish cramps, but it was not the unbearable pain others have described it as. i had some cramps throughout the day, but mainly in my back. overall, i would rate today&#039;s pain as a 3/10."
