One cause for having an abnormal early menstrual period is psychological. Although it is not too common for psychological problems to disrupt the normal period cycles, it can happen. Among the psychological problems that can cause problems with a womanâs periods are anxiety, fatigue and stress.

A physical problem that changes the hormone levels in the body will disrupt ovulation, which will cause an early menstrual period.
