Plan B works by preventing ovulation by about 5 days. However if yours only worked for 3 days and if you ovulated on the 29th or 30th, it wouldn't have protected you. You still may be OK depending upon when you may have ovulated, but if you missed your due period, perform a pregnancy test 4 days later. Your gynecologist can advise you further.
