How to Calculate Your Menstrual Cycle

Calculating your menstrual cycle is straightforward. It begins on the first day of your period and ends on the first day of your next period. The length of a typical cycle is around 28 days, but it can vary significantly from woman to woman. Cycles ranging from 21 to 35 days are generally considered normal. Irregular cycles can make it more challenging to predict ovulation and plan for conception. If you're concerned about irregular periods, you might find our article on irregular period calculator helpful.

Using Our Ovulation Estimator

Our tool goes beyond simple cycle tracking. It helps you identify your most fertile days, also known as your fertile window. This is especially useful if you're trying to conceive. Input the first day of your last period and your average cycle length, and the estimator will:

  • Pinpoint your fertile window
  • Estimate your ovulation day
  • Provide an interactive six-month calendar that color-codes your period days, fertile window, and peak ovulation day

Planning for Pregnancy

Knowing your fertile window is crucial when planning for pregnancy. Understanding when you are most fertile helps maximize your chances of conception. Our tool also includes a pregnancy possibility calculator to assess the likelihood of pregnancy based on intercourse timing.

Tracking Your Pregnancy

Once you've conceived, our tool seamlessly transitions into a pregnancy calculator. You can determine your due date, track your current trimester, and monitor key milestones using your last period, conception date, or a known due date.
