Our implantation calculator is helpful with understanding when implantation may occur by entering when ovulation happened or your last period. Knowing when implantation occurred can help you plan to take a pregnancy test or identify whether symptoms you are experiencing are related to being pregnant! Implantation typically occurs between 7dpo (days past ovulation) and 11dpo.

How to Use the Implantation Calculator

Our implantation calculator is an easy tool to use. You simply enter your ovulation date to get a list of dates that highlight your best dates for implantation success. If you’re not tracking ovulation you can enter the date of your last period and your average cycle length to get the most accurate results.

As they say, “timing is everything”, and that couldn’t be more true than when trying to conceive. It can take a number of tries, and playing around with the timing of your cycle to get it right. Don’t be discouraged if you don’t get pregnant right away. Keep trying around the different days when you’re at your most fertile. Utilize our easy to use implantation calculator to help determine if symptoms you’re experiencing could be implantation and sign up for emails regarding fertility and more!

Understanding Implantation Calculator Results

The results are fairly simple to understand, the dates provided by the calculator are color coded and explained in the chart like you see here. The darker the red, the more likely implantation will occur or has occurred on those days if you are to get pregnant.

In this example, if ovulation occurred on January 15th, the most likely day for implantation would be Jan 23rd. The example shows this as the darkest red, and says “Most Common” next to it.
