The Billings Ovulation Method® was developed in the 1960s by the physicians Drs. John and Evelyn Billings. The couple were pioneers in fertility awareness. The Billings method is designed to be universal, meaning any woman can learn the method (visually impaired, no access to technology, low income or reduced literacy). The goal of the Billings method is to teach women to think of their fertility in terms of patterns that are dictated by the rise and fall of estrogen and progesterone. By identifying these patterns women are able to recognize their individual days of fertility (PEAK day) and infertility. The Billings Ovulation Method is based on rigorous science and is backed by more than 50 years of medical research.
