About NFP

Natural Family Planning is based on fertility awareness, the knowledge of a couple's fertility. It is a means of reading a woman's signs of fertility and infertility.

The Couple to Couple League teaches three basic signs of fertility - temperature, mucus and cervix - and how to apply these signs in the Sympto-Thermal Method (STM) of NFP, which can be used either to achieve or to avoid pregnancy.

NFP can be used throughout a woman's fertile life, including during the premenopause and the return of fertility after childbirth

Modern NFP is far more advanced than the early NFP methods, such as Calendar Rhythm, which were outdated 60 years ago, but are often still referred to by people who are unaware of modern developments.
