Any medical intervention which prevents a pregnancy from occurring in case of unprotected sexual intercourse is a contraceptive method. Then what is emergency contraception? Essentially emergency contraception is an emergency measure taken to prevent pregnancy when a regular method of contraception fails. The key word here is regular method . Emergency contraception cannot be your regular method of contraception!! It is not right for your body and will not work effectively. Often time s young and older women alike rely on emergency contraceptive pills as their primary method of contraception which as expected results in frequent failures and accidental pregnancies.
