I took emergency contraception last sunday, the 11th. i was supposed to have my period around the 14th, but still havent had my period. am i pregnant?

Maybe: You should definitely take a home pregnancy test to find out. However with the hormones that you have taken, it is not unusual that your periods will be irregular for a few months

Less likely...: Emergency contraception can delay the start of your period. Most likely you aren't pregnant. But if you want to know for sure, do a home pregnancy test and find out. They are available at the pharmacy without a prescription. Best wishes!
