What cause my period to come 5 days early when it is always on time?

Irregular menses: Menstrual cycles duration and frequency can be affected by stress, illness, infections, nutritional status, exercise and number of other factors. A single episode of an earlier than normal menses may be related to one or more of these factors. A single episode is not concerning.
