What range of menstrual cycle flow is considered to be normal?

We time periods from the first full day of menstrual loss as Day 1. The menstrual cycle duration is timed from the first day of one period to the first day of the next. We consider menstrual cycles of less than twenty-one days to be too short, and they are too long if the cycle exceeds 35 days. The first day of the last period is called the last menstrual period or LMP.
