A Thinking Women's Guide to Better Birth
I read this book while pg too - Loved it. (Though it was very full on for a first birth, LOL! I had no idea I would want to be so... 'empowered' )

ETA: Gracie, I'm sure you did what you did in order to protect your baby and that's all you can do. If you wanted to continue to wait beyond 42 weeks, like Michael said, you can have regular scans to show that bubs is ok. And there are natural ways to try to get labour going (not saying you hadn't tried those already - I don't know your story and so possibly you did all that.) But I hear that is such a hard road when you're going through our hospital system. You are under a great deal of pressure.
