What food can act as an emergency contraceptive? there isnt any ecpills here in my country

There's no such food: It would be fascinating if certain food items could prevent pregnancy, and would likely be hazardous to the human race, too. A woman can get an IUD, which prevents pregnancy after sex, and continues to work for many years into the future. A woman can also get birth control pills, and ask her doctor how to take them to mimic an Emergency Contraception effect. See the site http://ec.princeton.edu
