The pill works in several ways to prevent pregnancy. The pill
suppresses ovulation so that an egg is not released from the
ovaries, and it changes the cervical mucus, causing it to become
thicker and making it more difficult for sperm to swim into the
womb. The pill also does not allow the lining of the womb to
develop enough to receive and nurture a fertilized egg.This method
of birth control offers no protection against sexually-transmitted
diseases.
