Understanding Your Menstrual Cycle

The menstrual cycle is typically counted from the first day of one period to the first day of the next. While the average cycle length is 28 days, a normal cycle can range from 21 to 35 days. Factors such as stress, diet, and underlying health conditions can affect cycle length and regularity. Tracking your cycle over several months can help you identify patterns and better predict your next period.

How a Next Menstrual Cycle Calculator Works

A next menstrual cycle calculator estimates the start date of your next period based on the information you provide about your past cycles. Typically, you'll need to input:

  • The first day of your last menstrual period.
  • The average length of your menstrual cycle.
  • The duration of your period.

Based on this data, the calculator estimates the start date of your next period and provides a calendar view of your upcoming cycle. Note that these calculations are estimates and may not be 100% accurate, especially if your cycle is irregular.
