There’s no such thing as one-size fits all healthcare, and Natural Family Planning is no different! There are 3 main Natural Family Planning methods, with several groups teaching their own version of each method. Each one has its own strengths and weaknesses, but they all share very similar success rates (for more information about the success rates of Natural Family Planning, see our post: Does NFP Work?).

Natural Family Planning Methods

Why are there so many Natural Family Planning methods? Because no two are exactly alike and some women find that one method works better for them than others. Some women prefer to track multiple signs of fertility, while others prefer focusing on just one. And as Mandi explained in her article “It’s Ok to Change NFP Methods“, many couples switch methods as their life circumstances change.

So what are these methods? As we said, there are 3 main methods: Mucus-only, Sympto-Hormonal, and Sympto-Thermal. The Sympto-Thermal method (STM) is possibly the most well known method, thanks to Toni Weschler’s amazing book, Taking Charge of Your Fertility. Below, we’ve listed each method and corresponding groups underneath. If you need some help deciding which method works best for you, you can take our fun and easy quiz!

Mucus Only Method

These methods teach the careful observation and charting of the absence or presence of cervical mucus throughout the day.

Sympto-Hormonal Method

This method of NFP teaches women how to use an at-home fertility monitor to measure daily levels of reproductive hormones, as well as to observe and chart cervical mucus.

Boston CrossCheck Method

Sympto-Thermal Methods

These methods of NFP are also referred to as “cross check” methods because they teach the careful observation and charting of cervical mucus, basal body temperature (BBT), and the optional cervix sign.
