How does emergency contraception work?

Answer

The Emergency Contraceptive Pill (ECP) can delay ovulation (the release of an egg from a woman's ovaries) until all the sperm are dead, so that no egg can be fertilised.

Or, if ovulation has already taken place, it may stop a fertilised egg from implanting in the womb.

There is less evidence to support this effect.
After you take the ECP you also need to keep on using other contraception until your next period in case you ovulate AFTER taking the Emergency Pill.

Otherwise you could still become pregnant.

Of course, the ECP does not protect you from sexually transmissible infections (STIs).
