The practice itself is fairly easy, and once learned, the simple process of observation and recording takes only a few minutes each day. However, you do have to invest some time in learning Fertility Awareness (FA). You can read about it endlessly, but to learn to practice it, you need to actually observe your cycles, as they are happening. A learning period at least 3 months should be anticipated. Moreover, FA is not right for everyone. It requires a daily commitment, and having a stable lifestyle (relatively consistent wake up times, limited amounts of travel & partying) will make the practice easier. Finally, there are phases of life, most notably during adolescence, after the birth of a baby, and around the time of menopause, when FA can be challenging. Experienced instruction can help you through those rough spots. For those who find Fertility Awareness to be a good fit, FA is easy to practice and rewards users richly for their efforts.
