Natural Family Planning

What is the Billings Ovulation Method™?

The Billings Ovulation Method™ is a method of natural family planning that teaches women to recognise their own individual pattern of natural fertility and infertility. Developed by Drs John and Evelyn Billings more than 50 years ago, it has since been scientifically researched and validated by scientists all around the world. The Billings Ovulation Method™ can be used in all the different circumstances of a woman’s reproductive life, irrespective of the length or regularity of her cycle.


Understanding your Fertility

Whilst men are fertile all the time, women are fertile for only a few days during their cycle. Most women are unaware of the natural signs that indicate their fertility. The Billings Ovulation Method™ can teach couples to recognise their joint fertility, giving the couple the knowledge they need to confidently make decisions about the avoidance or achievement of pregnancy.


There is no method of avoiding pregnancy which is always 100% effective. When the Billings Ovulation Method™ is properly understood and applied according to the rules for avoiding pregnancy, it is highly effective. Latest trials show greater than 99% effectiveness.

In a group of 207 women who previously were classified as infertile, 65% were able to achieve a pregnancy after learning the Billings Ovulation Method™ to identify their peak fertility.
