Understanding your menstrual cycle is crucial for family planning, whether you're trying to conceive or avoid pregnancy. The menstrual cycle is typically 28 days, but can vary significantly between individuals. Knowing your cycle length is the first step in calculating your fertile and infertile days. You can use our tool to help you calculate where you are in your cycle, or if you are trying to become pregnant.

Estimate Your Fertile Window Now →Identifying Your Fertile Window
The fertile window is the period during your menstrual cycle when you are most likely to get pregnant. This window includes the days leading up to ovulation, the day of ovulation, and a day or two afterward. Sperm can survive in the female reproductive tract for up to five days, so having intercourse in the days before ovulation can lead to conception.
Ovulation typically occurs about 14 days before the start of your next period, but this can vary based on your cycle length. To pinpoint your ovulation day, subtract 14 days from the length of your cycle. For example, if your cycle is 30 days long, ovulation likely occurs around day 16. Our ovulation calculator can help you estimate your ovulation day.
Calculating Fertile Days with Our Ovulation Estimator
Our Ovulation Estimator is designed to help you easily identify your fertile window. By inputting your cycle length and the first day of your last period, the tool provides a personalized six-month calendar. This calendar color-codes your period days, fertile window, and peak ovulation day, making it simple to visualize your cycle and plan accordingly.
Identifying Infertile Days
Infertile days are the days in your cycle when pregnancy is very unlikely. These days typically fall outside the fertile window. However, it's important to note that no method of contraception is 100% effective, including relying on infertile days. Sperm can survive for several days in the reproductive tract, and ovulation can sometimes be unpredictable.
Using Our Pregnancy Calculator for Planning
In addition to the Ovulation Estimator, our tool also functions as a pregnancy calculator. If you are trying to conceive, you can use the pregnancy calculator to determine your due date based on your last period, conception date, or known due date. It provides personalized timelines and predictions to help you navigate your pregnancy journey.
