How to Calculate the Cycle Length

  1. Start counting on the first day of your period.
  2. Count up to the day before you start your next period.
  3. Monitor your cycle for at least 3 months.
  4. Calculate your average cycle length.
  5. Continue to track your cycle.

Begin on day one of your period and count the number of days until your next period, which is day one of your next cycle. Track for 3 months and add the total number of days. Divide that number by three and you'll have your average cycle length. Ovulation normally occurs 12-16 days prior to your period.Mar 25, 2019
