What is fertility awareness (FAM)?
Fertility awareness (also called natural family planning or rhythm method) is a way to predict fertile and infertile times in your cycle. FAM is based on body signs, which change during each menstrual cycle in response to the hormones that cause ovulation (the release of an egg). If you use FAM and don’t want to get pregnant, you must abstain (not have intercourse at all) or use another contraceptive during your fertile times.
