What is an ovulation predictor?

Ovulation is the period when the ripe egg is released from the ovaries and travels along the Fallopian tubes to meet the sperm and become fertilised. The most fertile period of the menstrual cycle is therefore during the 3 days prior to, and including ovulation because any sperm present in the tubes will have the best chance of fertilising the egg when it has just been released. Therefore, an ovulation calculator is an accurate indicator of the fertile period.
Ovulation calculators can be simple applications to predict when you ovulate during the month, or expensive kits that measure the rise in luteinising hormone (the hormone that triggers ovulation). If you want to get pregnant naturally, your best bet is to try during this period.
Didn’t get pregnant after 12 months with the ovulation predictor?  We recommend you talk to an infertility specialist as soon as possible.

    i just married before three months bt not able to successful concieve and is feeling irregular period since when get maturity in age of 14 years. how it be regular? what is posible way to judge most fertile days?

    • Dear Jesif

      If you have irregular periods, the best advice is to visit a gynaecologist to discover why. An ovulation predictor is not useful in these circumstances.

    please help me i have been trying to get pregnant for 3 yrs now.

    • Dear madam

      You should have your fertile period between 20 and 25 June.

      If you have been trying for 3 years, i suggest you and your husband go to a doctor for a check up.

      Good luck!

    Will ovulation predictor strips be reliable whilst breastfeeding?

    • During breastfeeding, your body produces prolactin, which tends to inhibit ovulation. But, since this is not total, you can still ovulate. Ovulation predictor kits will remain accurate.

    I am currently struggling to conceive plus I have 2 ovulation prediction calculators plus they both provide me 2 different days of ovulation. What does this mean? I input the same information inside both of them.

  10. Michael K says:

    My ovulation calculator states day 1 a little fertile, day 2 fertile, day 3 quite fertile, then day 4 time for ovulation. Can we try to conceive on the fertile days or simply the ovulation day??
