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!!

    I am 31, have had a horrible time trying to carry a baby. i have had 3 miscarriages total and one being this past february. I am actively trying to conceive and my dr tells me i am good to go. The first day of my last period was May 1st and ended on the 4th. I am very regular. and do not have complications on my monthly. However, due to the ovulation calendar, my ovulation day was May15th, which me and my husband had intercourse every day for 4 days prior to the 15th and every day for 3 days after the 15th. I am also B Neg blood type which means i have to get a injection IMMEDIATELY after finding out i am pregnant. When is a good time/window for me to take a pregnancy test?

      I’m so sorry to hear about your losses, Kasey. I have miscarried before as well and know how bad it hurts. 🙁 Has your doctor run blood tests to determine your progesterone and estrogen levels to make sure that everything is normal there? This is something a friend recently had tested after two miscarriages and they found she had hormone issues which were likely causing her to miscarry.
      In regard to your recent attempt, I would recommend waiting to take a test until after your missed period. Best wishes!

    Hi.. My last menstrual was on the 5th of April I am trying to figure out when I ovulated and also we had unprotected sex from the 19th of April until the 29th… I took two pregnancy tests on the 28th and 29th and they came out negative. My next menstrual is expected on the 3rd of May. My breasts are heavy and sore and I’m also experiencing some slight cramping but no period as yet. Did I take the tests too early? Would I be pregnant? When should I test?

      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!
