How Does Anya Work?
Anya works just like the regular 21-day cycle oral contraceptive: it uses a combination of hormones to prevent ovulation from occurring, thus preventing pregnancy. It also thins the lining of the uterus, possibly preventing the implantation of a fertilized egg. What distinguishes Anya from other types of birth control pills, though, is the fact that you take a hormonal pill every single day of the year.
