@whois1230 As someone who received their Kyleena IUD this morning, I can vouch for most of this as being my experience as well! The details are all very much the same, with the following exceptions:
I was provided a single tablet to take 5 hours prior to my appointment to assist with cervix dilation.
I did not take ibuprofen prior to my appointment (I thought I did, got home afterwards, and realized I completely forgot) - which allowed me to experience the pain for what it was: equivalent to my moderately intense period cramp pains - which I was able to disassociate from when I focused on controlled breathing. Please understand, though, that unlike OP, this was completely indistinguishable from my regular period pain (location and pressure and sting felt exactly the same). Sortof related, for reference, I will experience incredible cramping and pain during my periods, usually resulting in side effects like extreme nausea, dizziness, headaches, back pain, doubling over, and also taking time off work. The Kyleena insertion was somewhere between small cramping pain and this extreme pain.
It only took 2 minutes, and 6 hours later I am still experiencing cramps with ibuprofen taken 5 hours ago, but very, very lightly. It was a genuinely positive experience overall and I am proud of myself for making the decision to get an iud.
Edit - sentence structures and explanations.
