Emergency Contraceptive Pills (ECPs) should be used within 72 hours of unprotected intercourse or during the failure of any contraceptive method.

If you miss two or more regular birth control pills, you should also consider taking ECP the morning after.

It cannot be consumed regularly as it has adverse side-effects including ectopic pregnancy (pregnancy outside the uterus) after long term use.

ECP is not a regular contraceptive pill
