Clearblue® Ovulation Calculator Plugin

Embed our ovulation calculator to enrich your fertility content.
Knowing the most fertile days in a cycle can increase a woman’s chances of conceiving and knowing the likelihood of ovulation on a specific day may help women understand their fertile window. This ovulation calculator tool estimates the days on which a woman is most likely to ovulate.
Currently, our tool only works for WordPress, but this plugin will be available on other platforms shortly.

What is an ovulation calculator?

An ovulation calculator estimates how likely a woman is to release an egg on a particular day in her menstrual cycle.

How does the ovulation calculator work?

The ovulation calculator takes the date the last period started and the average cycle length to estimate when a woman is most likely to ovulate. Results are based on information provided and on data from the following publication: Sarah Johnson, et al. Current Medical Research and Opinion (2018) DOI:10.1080/03007995.2018.1475348

How to use the ovulation calculator?

1. The user enters the first day of the last menstrual period on the calendar.
2. The user enters the average cycle length from the drop down list.
3. The user clicks ‘calculate’.

How will results be displayed and what do they mean?

Once the data is entered and ‘calculate’ clicked, a calendar will be displayed showing the days on which ovulation is likely marked in purple together with a percentage. This is a percentage chance of ovulation on that day based on the inputted data.

Can I rely on an ovulation calculator?

An ovulation calculator estimates the potential ovulation days by taking the average cycle length and the date of the last period – basically the calendar method. It should be used for informational purposes only.
Detecting personal fertility hormones by using ovulation tests is a more accurate method to identify fertile days.
Ovulation tests are 2x more accurate than calendar method [1].

[1]: Study of 101 women in the UK comparing a simple calendar method to likelihood of conducting a test on LH surge day (2011).

How is an ovulation calculator different to a fertility calendar?

• An ovulation calculator estimates the likelihood of ovulation happening on a particular day.
• A fertility calendar indicates the days when sex is likely to result in conception.
