Ovulation Calculator

Are you trying to get pregnant or planning on it in the near future? If so, you can greatly improve the likelihood of getting pregnant by determining when you will ovulate next. Ovulation is the release of a female's ripe egg from her ovary. When this occurs, you are the most fertile.

Use our Ovulation Calculator to estimate your next ovulation date; simply enter the first day of your last menstrual period and the average length of your cycle. Because our tool provides you with only an estimate, consider yourself the most fertile during the period of 3 days before and 3 days after the estimated ovulation date. Best of luck!!

      Hi Ana – You’ll need to put in the first day of your last period and the average length of your cycle to find out when you likely ovulated. Best wishes!

    (Am trying to conceive) My last period was on 4-7th of April I had 10- 15th
    Of the same month …Is there a chance of getting pregnant?
    And pls when is my most fertile days?

    • Profile photo of Megan KlayEditor Megan Klay says:

      Hi Adaora – I’m not understanding… You had your period on 4/4-7 and again on 4/10-15? You’ll need to input the first day of your last period and your average length between cycles (last day of one to the first day of another) into the calculator to get your estimated ovulation date. Best wishes!

      Hi there – You’ll need to input the FIRST day of your last period then the average number of days between your cycles (last day of one period to the start of your next) to obtain your most likely ovulation date. Best wishes!

    • Profile photo of Megan KlayEditor Megan Klay says:

      Hi Jenely – Just record it! There are a few free apps out there, or you can just note in your calendar the first day of your cycle one month and the first day the month following, and that is the time between. Best wishes!

    My pierod came on on the 2nd of February and when off on the 7th of February I’m trying to find out when I will start ovulating can someone please help me??

    • Profile photo of Megan KlayEditor Megan Klay says:

      Hi Erica – How many days do you typically have between periods? If it’s 28 days, then our tool estimates you’ll be ovulating tomorrow, 2/16.
      Our Ovulation Calculator uses the first day of your last menstrual period and the average length of your cycle to calculate your estimated ovulation date. Because our tool provides you with only an estimate, consider yourself the most fertile during the period of 3 days before and 3 days after the estimated ovulation date. Best of luck!!
