Ovulation calculator

Calculate the best time to conceive

Using the calculator below will give you a good indication on when the best time is to conceive. This calculator assumes that you have a regular menstrual cycle and that you are of good health.

What is your fertile window?

Your fertile window refers to the most fertile days in your menstrual cycle which give you the highest chance of conceiving. The most fertile days in your cycle are the days leading up to ovulation before the egg is released from the ovary. For this reason we recommend couples have regular sexual intercourse every couple of days throughout the fertile window.

What if you have irregular cycles?

If your cycles are irregular or your cycle length varies from month to month it may be difficult to calculate your ovulation date in which case follicular tracking may be useful.

When to seek help?

If you have been trying to conceive for 12 months or more and not been getting pregnant, we recommend booking an appointment with a fertility consultant.
