Variability of cycle: Variability of menstrual cycle lengths is highest for women under 25 yrs. Of age. Having a cycle 3 days late, in a 21yo female is very common and the bleeding period can also vary. This all fall within the normal range. So, not much to worry at this point. The menstrual cycle is most regular from ages 35-39. The variability increases for women between the ages of 40-44. Thanks.
