To calculate menstrual cycle length, you count the number of days from day one of your period (CD 1) up to, and including, the day before the next period starts. The count does not include the first day of the next menstrual period, because that's Cycle Day 1 of the next cycle.

Day 1 is the first day of your period. Since the length of your cycle can vary slightly from month to month, itâs best to keep track for a few months. Once you have an average, subtract 18 days from the length of your shortest cycle. This is the first day youâre likely to be fertile. Next, subtract 11 days from the length of your longest cycle.
