Natural Fertility Awareness

The Billings Ovulation Method

The Billings Method (BM) is a scientifically validated method of Natural Fertility Awareness pioneered by Melbourne Medical doctors John and Lynn Billings. They carefully researched the observation of the cervical mucus symptom as a marker of ovulation. The science of the method was validated by Kiwi pathologist Professor Jim Brown who at the time was also Melbourne based. He measured daily levels of reproductive hormones in hundreds of menstrual cycles in women of all ages. This validation has placed the BM uniquely in being able to be used by women with irregular cycles, in all life’s stages. Regular follow up by an accredited BM teacher is essential for the effective and precise practice of the method. Being taught how to accurately chart daily observations of fertility and infertility is essential.
