Taking Charge of Your Fertility by Toni Weschler (hope that is spelled right). Highly recommended whether you're trying to conceive (or not!) or just want to become more educated about your body.
I read all the fertility/pregnancy books since DH and I struggled with infertility for many years (finally got pregnant on our second IVF, but I miscarried; 7 years later we are, amazingly, quite content being childfree), and this was the best book of the lot.
Good luck!
