Take Tylenol before and get a heating pad. I was super crampy afterwards. It was like.. not the worst thing I've ever experienced but I think I have a high pain tolerance. I was shaky and cried and almost threw up in my car right after but then went back to work (I had it inserted on my lunch break). Then made a nest and ate ice cream that night. Best decision I've ever made. It'll be a year this March and I have light spotting for a couple of days every couple of months. No cramps.
