fertility awareness method of preventing or achieving pregnancy for Luschka of Diary of a First Child! She's doing a whole series on various contraceptive methods, their pros and cons, and user experiences of them, and my post on the FA method is up today.
I hope you'll go over to Diary of a First Child and check out my post about Basal Body Temperature (BBT) charting as a cheap and hormone-free way to get in touch with (and in control of) your fertility. (Of course, if you don't enjoy reading about the female cycle and learning more than you probably wanted to know about my fertility, please feel free to skip this one altogether. ;)
