Why Track Your Menstrual Cycle?
A typical menstrual cycle lasts about 28 days, but it can range anywhere from 21 to 35 days in adults. Tracking your period helps you understand your body’s natural rhythms, alerts you to potential health irregularities, and makes planning vacations or special events much easier.
