Reply welcomes patients using any fertility awareness method, and our fertility educators teach four methods in-house: Listen Fertility, Sensiplan, Billings, and Marquette. Fertility awareness can be used for health monitoring and management, or to help become pregnant or prevent pregnancy. Visit our fertility awareness page to learn more.

Welcome to the Billings Ovulation Method!

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.

Billings is considered a cervical mucus only method, meaning it tracks the sensations of cervical mucus at the vulva. It can be used by couples trying to become pregnant, couples trying to prevent pregnancy, or by patients for health monitoring and management.
