Effectiveness

With proper training and use, the Billings Ovulation Method® has been verified as 99% effective for avoiding pregnancy.   It’s effectiveness is comparable to the most effective forms of hormonal contraception, but without any of the risks or side effects.   The Billings Ovulation Method® also has higher effectiveness than IUDs and barrier contraceptives.

The method-related pregnancy rate is achieved when couples follow all the instructions for the method of birth control.

The use-related pregnancy rate includes couples who did not follow or misunderstood the instructions of the method of birth control.
