What it is?

Emergency contraception is used if other contraceptive method fails (for instance if a condom splits or a pill is forgotten or taken late) or no contraception at all is used. This form of emergency contraception consists of 1 pill containing a special dose of the hormone progestogen. Emergency contraceptive pills can be used up to 72 hours (three days) after sex.

How it works?

You will be given one pill, which should be taken as soon as possible after having unprotected sex, and no later than 72 hours after. Emergency contraceptive pills work in several ways. They may stop ovulation (release of an egg), they may stop an egg from being fertilised or they may stop a fertilised egg from implanting in the womb.
