I wasn't even sure I was having contractions to begin with, because they honestly didn't hurt at all. (Although it sure hurt later LOL).

I just wanted to respond to your request for a book about the "best way of pushing". You really don't need to know HOW to push, it's not something you have to consciously direct. Your body will push all on its own, and it knows exactly how to do it. It just happens when you're ready.
