This comprehensive book explains in lucid, assured terms how to practice the fertility awareness method (FAM), a natural, scientifically proven but little-known form of birth control (which is not to be confused with the woefully ineffective "rhythm" method). As the book explains, by using simple fertility signs including peaks in morning body temperature and changes in cervical position and cervical mucus, it's possible to determine when ovulation is taking place. Fertility awareness is therefore useful for not only couples who are trying to conceive, but for those who are aiming to avoid pregnancy without the use of chemical contraceptives.
