Can the Billings Ovulation Method™ be used to postpone pregnancy?

Yes. In the average cycle, there is only a window of fertility. Without the use of drugs and devices, couples using the Billings Ovulation Method™ can confidently identify times when pregnancy is impossible. Couples using the Billings Ovulation Method™ simply abstain during times of possible fertility. There are three rules to follow before ovulation (if pregnancy is to be postponed) and one rule after ovulation. Once couples understand the woman's cycle and how to apply the rules, they can use this method until the woman reaches menopause.
