What are Fertility Awareness Methods?
Fertility awareness methods (FAMs) are ways to track your ovulation so you can prevent pregnancy. FAMs are also called "natural family planning” and “the rhythm method.”

What are the different kinds of FAMs?
Fertility awareness methods help you track your menstrual cycle so you’ll know when your ovaries release an egg every month (this is called ovulation).
The days near ovulation are your fertile days — when you’re most likely to get pregnant. So people use FAMs to prevent pregnancy by avoiding sex or using another birth control method (like condoms) on those “unsafe,” fertile days.
There are a few different FAMs that help you track your fertility signs. You can use 1 or more of these methods to predict when you’ll ovulate:
The Temperature Method: you take your temperature in the morning every day before you get out of bed.
The Cervical Mucus Method: you check your cervical mucus (vaginal discharge) every day.
The Calendar Method: you chart your menstrual cycle on a calendar.
It’s most effective to combine all 3 of these methods. When used together, they’re called the symptothermal method.
The Standard Days Method is a variation on the calendar method. You track your menstrual cycle for several months to figure out if your cycle is always between 26 and 32 days long — you can’t use this method if it’s longer or shorter. Once you’ve established that your cycle is in the right range, you use another form of birth control (or don’t have vaginal sex) on days 8-19, which is when you’re fertile.
