resp:524 It does that too. This is from the FDA's PlanB website
" Plan B works like other birth control pills to prevent pregnancy. Plan
B acts primarily by stopping the release of an egg from the ovary
(ovulation). It may prevent the union of sperm and egg (fertilization).
If fertilization does occur, Plan B may prevent a fertilized egg from
attaching to the womb (implantation). If a fertilized egg is implanted
prior to taking Plan B, Plan B will not work. "
