The Fertility Awareness Method (FAM) is a natural method of determining whether a woman is fertile or infertile by observing simple body signs and applying a few rules of interpretation.
FAM has been used for over 30 years as a natural method of birth control by hundreds of thousands of couples around the world. With the Internet, its practice has spread even more quickly among those trying-to-conceive, since it pinpoints when a woman is most fertile, when ovulation has most likely occurred, and when you might be pregnant. Because of its efficacy in identifying fertility, FAM can reduce the time it takes to successfully conceive from an average of 6 months to 2-3 months.
FAM is based upon the fact that certain simple body signs change with changes in a woman's menstrual cycle. Specifically, waking temperature (also referred to as basal body temperature) and cervical fluid (also referred to as cervical mucus) change predictably and identifiably with changes in the hormonal cycle that accompanies ovulation during each cycle. Users of Taking Charge of Your Fertility Software simply observe and record these changes and the software then analyzes them to determine your fertility, to estimate your date of ovulation, and to determine if you might be pregnant.
