The term “fertility awareness-based methods” (FABM) refers to different ways of determining fertile and infertile phases of the female cycle and can be used for family planning.
The basis of all fertility awareness-based methods relies on a woman´s understanding and recognition of her fertility! Therefore the exact determination of the fertile and infertile days in a woman’s cycle based on her natural physiological signs. FABM provide couples exact with the information they need to identify the days in each cycle when the woman is likely to conceive.
In doing so, couples know the different phases of the female menstrual cycle in which a pregnancy can occur. Couples can use this information to specifically plan a pregnancy.
There are different ways and methods that women can use to determine their fertility. These include the temperature method, cervical fluid method, calendar method, symptothermal method and symptohormonal method.
As a reliable lifestyle fertility tracker, in the terms of FABM, Daysy calculates the fertile phase of the woman’s cycle based on a very sensitive and precise, computer-assisted basal body temperature measurement, obtained directly after waking up.
Daysy’s integrated thermometer enables a particularly precise measurement. This distinguishes Daysy from other methods which require a separate basal thermometer, leaving it up to the user which thermometer is used: consequently, there is no guarantee that the applied thermometer meets the required standards. Measurement inaccuracies and rounding errors can occur due to the thermometer or when entering the data into the app.
