Levonorgestrel
"I had mine inserted on Nov 27th 2009. I am 27 and have never had kids. Insertion was a bit painful for me since I have never had kids and my cervix is small (I was told it was small by the doctor). But I was given Percocet and after about 35-40 min it started to ease my cramping, along with a heating pad. There was no numbing agent used and I was glad that my sister drove me home, and that I didn't have to return to work afterwards. I've only had some cramping in the last couple of days and spotting is occurring here and there. Today is the least amount of spotting I've had which is 4 days later. Have not had sex yet after insertion and am hoping that it is not painful."
