Please tell me about advantages and disadvantages of the morning after pill?

Emergencies: The advantage of the morning after pill is that it can delay ovulation so you don't get pregnant if you had one episode of unprotected intercourse. Its disadvantage is that it only works once each month. If you are in a relationship having sex ever few days, it won't protect you. It isn't as effective as a standard birth-control pill and can have side-effects such as Nausea. Best wishes!

Simple answer: Advantage- Taking it after unprotected intercourse to prevent unintended pregnancy. Disadvantage-Using the pill as a primary contraceptive.
