Understanding Menstrual Cycles

A menstrual cycle is the time from the first day of one period to the first day of the next period. The average cycle length is 28 days, but it can vary from 21 to 35 days among different women. Tracking your cycle length can help you:

  • Understand your fertile window for family planning
  • Identify any irregularities in your cycle
  • Recognize early signs of potential health issues

Example Calculation

If your average cycle length is 35 days:

Weeks = 35 days / 7 days/week = 5 weeks

This means your cycle spans approximately 5 weeks.
