Natural Family Planning (NFP) is a system of regulating fertility based on knowledge of a woman's cycle. The system is also called Fertility Awareness because it can be used to help a couple prevent or achieve a pregnancy. Using no artificial hormones, chemicals or barriers, Natural Family Planning can help couples postpone a pregnancy with 95-98% effectiveness. To achieve the best effectiveness, couples should be trained in one of the more scientifically-based methods of NFP (See links below).
Training varies by method but can include one-on-one instruction, classes or online education.
