Use Of The Morning-After Pill
Considered a form of emergency contraception, the morning-after pill works by preventing or delaying ovulation or blocking fertilization of the egg. It may also prevent implantation of a fertilized egg in the uterine wall. Although some brands of the morning-after pill are available over the counter without a prescription, it's important to learn more about how and why it works, its effectiveness, and the possible side effects.
