Sounds normal: When you take a morning after pill, it can alter the subsequent period. You can have early bleeding or late bleeding, or prolonged spotting. These symptoms should resolve after your next 1-2 menstrual cycles. To be 100% safe, you may want to take a pregnancy test now, and again in a week or two, since this period may not be normal.
