Ovulation Calculator
Trying to get pregnant? Our Ovulation Calculator helps you determine the days you're most likely to conceive.
If you're actively trying to get pregnant, knowing when you will ovulate will greatly enhance your chance of success!
Our Ovulation Calculator will help you predict the dates you're most likely to ovulate based on your cycle length. Use this calculator as your guide for when to start testing with The FIRST RESPONSE® Easy-Read Ovulation Test, which is over 99% accurate in predicting the 2 days you're most likely to become pregnant.
Enter the day of your last period and the number of days in your cycle (anywhere from 20 to 45 days). Our Ovulation Calculator will tell you the 2 days you're most likely to conceive.
Please note: These dates are approximate and are best used as a guideline for when to begin testing with the FIRST RESPONSE® Easy-Read Ovulation Test. Additionally, these dates are based on a regular menstrual cycle. If your menstrual cycle is irregular, you may have more difficulty pinpointing your day of ovulation based on the calendar alone. With our Daily Ovulation test, you can test daily for 20 consecutive days from the day after your period ends.
