Nothing: Absolutely nothing abnormal about a four day period that starts when it is scheduled. Actually, it is not the norm to bleed for 8 days. If the shift bothers you or you are concerned about being pregnant, that is easy to fix... Get a urine pregnancy test, but I do not think it is indicated.
