Levonorgestrel
"I got Kyleena inserted today July 7, 2017. I was very impressed with the procedure. I was shaking before going in because I read reviews that said it hurts so bad you'll cry. I did not experience that! I felt two cramps that felt like my period just started and it took 2 minutes! If you can get through a Pap smear you can get through getting it inserted. Just breathe and talk to your doctor through it and take 600 mg of Ibuprofen before and you'll do fine. Also buy a heat pad for after because you will experience some cramping. I am still having some cramps and discomfort and it's almost been 24 hours but nothing unbearable. Give it a shot! I will update in about a month and see how everything is going."
