What are the side effects of emergency contraceptive pill

An emergency contraceptive pill, or the morning-after pill, is a method of contraception used during an emergency. It prevents unintended pregnancy, and the side effects of emergency contraceptive pills are not usually severe. Women who have had unprotected sex or whose birth control method has failed can use emergency contraception to avoid getting pregnant. The morning-after pill should be used as a backup method of birth control and not as the primary method. These pills work by delaying or stopping ovulation, which will prevent fertilisation and hence there will be no pregnancy.
