Billings Method

The Billings Method (BOM)--This effective natural method is based on the cervical mucus sign that a woman produces during her fertility cycles. Women are taught to observe for sensations the mucus produces at the woman’s vulva and the appearance of any discharge during their normal daily activities. Nothing special needs to be done. What separates the Billings Ovulation Method® from other natural and artificial methods is its simplicity based on solid research. Over 850,000 hormonal assays confirm that the four simple rules of the method work.

The BOM has incorporated the most current science behind the different types and functions of the cervical mucus and what constitutes all categories of Basic Infertile Patterns, to make the practice of this method more satisfying and effective, with less abstinence.
