Emergency contraception (EC) is a form of birth control that is used after unprotected sex or contraceptive failure to prevent pregnancy. EC can be taken as a pill or used as a copper intrauterine device (IUD) and is effective if taken within a certain time frame after unprotected sex.

The most common form of EC is the “morning-after pill,” which contains high doses of hormones similar to those found in regular birth control pills. The pill works by delaying or preventing ovulation, stopping a fertilized egg from implanting in the uterus, or by thickening the cervical mucus to block sperm from reaching the egg.
It’s important to note that EC should not be used as a regular form of birth control and is only intended for use in emergency situations. It is also not as effective as other forms of birth control, and regular use of EC can increase the risk of health problems. It is recommended to use a long-term form of birth control along with EC to ensure ongoing protection against pregnancy.
