I was really very scared to have an IUI done, but there's nothing to it. I read a lot and everyone kept comparing it to a Pap, well after all my infertility testing I couldn't even remember if a pap had hurt me or not. But really, most you'll feel is a pinch, if anything at all, and it's over in just about a minute. Good luck, I hope it works your first time, don't be nervous!
