I had it inserted this afternoon and I'm curious if its going to hurt at all. My doctor numbed me up really good and I didn't feel it go in at all. It's midnight and no pain at all right now. I was just wondering if the pain will come later so I can prepare myself for it. Also, if you have one, how long did the doctor say to use a back up birth control? I forgot to ask her today and I can't find anything online.
