More About the Fertility Awareness Methods

You can use the Fertility Awareness Methods to track changes in your body over the course of a menstrual cycle. This helps you find out which days you are likely to get pregnant. They work by helping you track your menstrual cycle and know when you are ovulating or when your ovaries release an egg. These are your fertile days. You can choose to not have sex or to use a barrier method (like a condom) on those days. If you have sex on fertile days or “unsafe” days, you are more likely to get pregnant.

There are many ways to track fertility, like daily tracking of body temperature, cervical mucus, and the days of your period. Your provider can help you learn more about these methods and support you in making the best choice for you.

How to Use the Fertility Awareness Methods

There are different ways to find out your most fertile days. Choose a method that works for you, or use more than one for better results. Talk with your provider to find out more if you think one of these methods could be the right choice for you. They can help fill you in on the details you will need to know to use these methods.

Standard Days Method (SDM) – Track your periods to find your fertile days. Your cycle must be between 26 and 32 days and always come on time to use this method. There are apps or special beads to help you keep track.

Cervical Mucus – Track the look and feel of your cervical mucus to find your fertile days. It’s best to use this method with the help of your provider so that you learn what to look for.

Two Day Method –  Look for any secretion of cervical mucus at least twice a day. If you found any cervical mucus, consider this a fertile day.

Basal Body Temperature – Take and record your temperature each morning before you get out of bed.

Symptothermal Method –  Track several of the signs your body gives that let you know when you are fertile. This can mean using more than one of these methods at the same time.

Breastfeeding Method – Breastfeeding a baby in the first 6 months after giving birth can serve as birth control.  This only works if certain rules are followed.

Fertility awareness methods range in effectiveness.

  • About 76-88% effective with typical use. This means that on average, 12 to 24 out of 100 women using these methods will get pregnant in a year. You can improve effectiveness by:
    • Talking to your provider about finding fertility awareness methods that work for you
    • Following the methods you choose and tracking changes in your body every day
    • Using abstinence or other birth control, such as condoms and spermicide, on your fertile days
  • 95-99% effective with perfect use. This means that if fertility awareness methods are used correctly all the time, 1 to 5 out of 100 women will get pregnant in a year.

  • It takes more work than other methods. You need to look for and record your body’s cues, such as changes in temperature, cervical mucus, and mood.
  • You need to have regular periods to use the Standard Days Method
  • You need to abstain from sex on fertile days if you want to avoid pregnancy, or use a barrier method like condoms. You should plan for at least a week each month when you don’t have sex or use a backup method.
  • It doesn’t work as well if you’ve just stopped using a hormonal method or an IUD. It takes a while for your body’s cycles to return to normal. Talk to your Family PACT provider to learn more.
  • You and your partner both have to be 100% on board in order to use these methods. It takes more cooperation than most other kinds of birth control.
