Fertility Awareness
How it works:
This is one of the most difficult birth control methods to use correctly. Your periods must be very regular for this method to work. Also known as natural family planning or rhythm method, the fertility awareness method prevents pregnancy by tracking your menstrual cycle and avoiding sex or using another birth control method during the fertile period surrounding ovulation, about 12 days every month. For most people, the fertility awareness method is 76-88% effective at preventing pregnancy.
