The morning-after pill is a form of emergency contraception that is most effective when taken promptly after unprotected sex. According to the references, it is recommended to take the pill within 72 hours (3 days) for the best chance of preventing pregnancy.

Timing: The sooner the pill is taken, the more effective it will be.
Effectiveness: The pill is designed to prevent pregnancy by stopping or delaying ovulation.

It is important to remember that the morning-after pill is not intended for regular birth control use and should only be used in emergencies. If you have any questions or concerns, it is best to consult with a healthcare provider.
