This book is highly recommended for both people trying to have a baby, and those trying to prevent it. It provides a lot of information about cycles and reproductive health, and actually gives you step by step information on using your body's cycle as a way to know when to try to conceive, and as a way to try to avoid pregnancy. This is a great read for anyone looking to get pregnant. I am indicating I would not buy it again because I already have it.... but I would buy it for a friend if I knew they were trying to conceive!
