Use our free ovulation Calendar to Find your Fertile Days
Understanding the days when you are ovulating will help you to calculate your fertile days. These are the days that conception is most likely. You may not have any ovulation signs and symptoms so understanding when you are actually ovulating can help increase your timing for getting pregnant.
How to use this ovulation calculator
Enter the first day of your last period and how long your cycle usually lasts (anywhere from 20 to 45 days) to calculate when you’re most likely to be fertile.
Your most fertile days will be shown in the ovulation calendar below including the first day you can test for pregnancy.
Once you have calculated your ovulation prediction you will have a better idea when you will be most fertile, but remember this is only an ovulation prediction so using an ovulation test on these days to confirm will help pinpoint your actual ovulation day. Using Conceive Plus during your fertile period and on the day of ovulation can also help increase your chances of getting pregnant naturally.
