The Ovulation Calculator predicts your most fertile days to increase your chances in getting pregnant.

For more information and tools designed for all hopeful, expecting and first-time mothers, you can also consult our Pregnancy Calculators section.

What are my most Fertile Days?

Depending on the information you provide concerning the date of  your last period, the Ovulation Calculator can predict your most fertile days and, therefore, the best days for conception. If you already know the dates of your first cycle, you can go onto your first fertility calender and calculate the period in which you are most fertile. 

These guidelines are based on the Calender or the Ovulation Calculator.

Is the Ovulation Calculator reliable?

Like any online calculator, the Ovulation Calculator is designed to help you and provide results which, as accurate as possible, will provide a starting point from which you can plan your pregnancy. If you are trying to become pregnant, we recommend that you compare the results of our Ovulation Calculator with those provided by direct sources, such as, an Ovulation Test which you can find at your nearest pharmacy.
