Fertility Awareness Based Method (FABM) is an umbrella term used for a list of unique natural birth control methods, each specifically designed to fit your personal birth control of choice.
The following list of natural birth control options are scientifically proven to be effective. They rely on barrier methods, or abstinence, to prevent pregnancy during each fertile window.
These birth control options do not require medication, internal devices or hormones to prevent pregnancy.
Fertility awareness, or the sympto-thermal method is practiced by daily tracking your cervical fluid, basal body temperature and optional cervix positions with the use of barrier methods, like condoms, a cervical cap or withdrawal during each fertile window, creating an effectiveness of 99.6%.
The Billings ovulation, or cervical fluid method is based on the daily observations of cervical fluid consistency at the vulva to determine if you are fertile.
By following this method’s rules, you have a 97% effectiveness of preventing pregnancy.
The basal body temperature method uses the observation of your daily waking temperature using a basal body thermometer.
By following this method's rules, you will have a 99% effectiveness in preventing pregnancy.
The standard days method identifies our fixed fertile window. The rest of the cycle is considered not fertile. This particular method is designed for people with cycles lasting 26-32 days.
You would use CycleBeads, a color-coded string of beads, to follow your fertile window for a 95% effectiveness in preventing pregnancy.
Technology has created tracking your cycle into an effortless task. There are a few fertility monitors and apps, like Daysy, solely designed to input your daily observations and temperature, which will then interpret if you are fertile or not.
It is highly recommended to NOT use an app alone for birth control, as some claim to predict ovulation. Only you can predict ovulation with your knowledge and personal observations. Apps become optimal if you choose to use them in conjunction with a Basal Body Thermometer or fertility monitor.
Fertility monitors are often designed to use the Basal Body Temperature Method of Birth Control and will automatically keep a record of your monthly cycles. With perfect use, this has an effectiveness rate of 99%.
The lactational amenorrhea method is a short-term method based on the natural effect that breastfeeding has on fertility. The act of exclusively breastfeeding suppresses the release of the hormones necessary for ovulation.
For 6 months after giving birth, if menstruation has not returned and the baby is exclusively breastfed, this method will provide 98% effectiveness in preventing pregnancy.
A kind reminder
The above methods of Natural Birth Control are NOT akin to the Rhythm Method, but are highly evolved forms of natural family planning. Each menstrual cycle varies from month to month due to stress or other factors, therefore cannot be predicted based on assumptions or previous observations. People intrigued in practicing fertility awareness based methods should take classes or receive professional introduction to ensure accuracy in the rules for achieving or preventing pregnancy.
