Fertility Awareness Methods
A hormone-free method that tracks ovulation signs to predict fertile days.
Fertility Awareness is not a single method but rather a group of methods. Fertility Awareness Methods (FAM) are also called natural family planning. FAM methods require you to track info about your body every day.
With perfect use, 1-5 out of 100 people will get pregnant over a year, depending on which FAM is used. Perfect use means you use the FAM as directed.
Most of the time, people don't use FAM exactly as instructed. This is called typical use. With typical use, 2-23 out of 100 people will get pregnant over a year, depending on which FAM is used.
FAM can be much more effective if you have help tracking your data. Currently, there is one FAM phone app approved by the U.S. Food and Drug Administration (FDA) called Natural Cycles. Based upon typical use, Natural Cycles is 93% effective.
You can also use a birth control method at the time of sex. We call this a Method Boost because it prevents pregnancy better than FAM alone. Method Boost options include outer condom (penile), inner condom (vaginal), pull out, spermicides, the vaginal gel (Phexxi), the cervical cap and the diaphragm.
FAM helps you predict when you will ovulate (release an egg) and when sperm can join an egg. These are your fertile days when you should avoid sex.
To figure out your fertile days, you need to track data about yourself every day: 1) your body temperature; 2) your period; 3) your cervical mucus (how thin or thick). To get the most accurate results, it is better to track all 3 of these if possible.
FAM only works if you can track your data every day. If pen and paper works for you, that is fine. There are also many online tools and smartphone apps.

You can get a thermometer and other supplies at a drugstore. There are several phone apps to help people use FAM to prevent pregnancy.
The Natural Cycles app is the only one approved by the U.S. Food and Drug Administration (FDA). The cost of use is about $100 a year. Cycle Beads is another popular FAM app.
