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 lifestyle.
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 the most commonly known FABM. It is practiced by recording daily 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. This method of natural birth control holds an effectiveness of 99.6%.
The Billings Ovulation Method, or cervical fluid method, is based on the daily observations of cervical fluid and vulva consistencies to determine the fertile window. This practice may resonate with people who do not have a regular sleeping schedule, or who travel regularly, and can not currently observe a consistent basal body temperature reading.
By following this method’s rules, we have a 97% effectiveness of preventing pregnancy.
The basal body temperature method uses the observation of daily waking temperature using a basal body thermometer. This method is sure to tell you when ovulation has occurred, therefore holding a high effectiveness of 99% in preventing pregnancy.
The standard days method identifies a fixed fertile window, where the rest of the cycle is considered not fertile. This particular method is designed solely 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.
Fertility monitors and apps for natural birth control and conception are designed to automatically keep a record of your monthly cycles. This has formed tracking your cycle into an effortless task. As you input your daily observations, the device will interpret if you’re fertile or not.
It is highly recommend to not use menstrual cycle fertility monitors or cell phone apps alone for natural birth control, as some claim to predict ovulation. These ovulation predictions can not be trusted 100% of the time. Only you can predict ovulation with your knowledge and personal observations. Apps are the most optimal if you choose to use them solely for record-keeping in conjunction with a basal body thermometer (BBT) or fertility monitor.
Fertility monitors are often designed to use both the Basal Body Temperature Method of Birth Control with a computerized algorithm, and will automatically keep a record of your monthly cycles.
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.
