The Billings ovulation method is a method in which women use their vaginal mucus to determine their fertility.[3] It does not rely on the presence of ovulation, rather it identifies patterns of potential fertility and obvious infertility within the cycle, whatever its length. Effectiveness, however, is not very clear.[3]
