What is the Billings Ovulation Method™? (BOM)

It is the original and most scientific method of recording daily hormonal profiles that uses a simple charting system developed by Drs. John and Lyn Billings. It is so effective and accurate the WHO gave it the name "Billings" to distinguish it from other methods. It has attracted top researchers in their fields who recognized its value, and who have conducted research with BOM throughout their careers over the past several decades. Many researchers feel this method is the most accurate and scientific. The Billings Ovulation Method has more worldwide studies and users than any other.
