A recent comment made me realize that I have not linked to this book here before. I consider it essential reading for every woman. Taking Charge of Your Fertility is an easy-to-read comprehensive owner’s manual for your reproductive system which will help you get pregnant or avoid pregnancy, to understand anomalies in your cycle, or to simply give you insight into the daily rhythms of womanhood. The book teaches you how to read your body’s own fertility signals, rather than the calendar. There is also a website which has (or had, it’s been years since I have been there) great and informative message boards. I’ll go add it to the list of links in the sidebar.
