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.<br />
Currently, our tool only works for WordPress, but this plugin will be available on other platforms shortly.</p>
<h4>What is an ovulation calculator?</h4>
<p>An ovulation calculator estimates how likely a woman is to release an egg on a particular day in her menstrual cycle.</p>
<h4>How does the ovulation calculator work?</h4>
<p>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</p>
<h4>How to use the ovulation calculator?</h4>
<ol>
<li>The user enters the first day of the last menstrual period on the calendar.</li>
<li>The user enters the average cycle length from the drop down list.</li>
<li>The user clicks ‘calculate’.</li>
</ol>
<h4>How will results be displayed and what do they mean?</h4>
<p>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.</p>
<h4>Can I rely on an ovulation calculator?</h4>
<p>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.<br />
Detecting personal fertility hormones by using ovulation tests is a more accurate method to identify fertile days.<br />
Ovulation tests are 2x more accurate than calendar method [1].</p>
<p>[1]: Study of 101 women in the UK comparing a simple calendar method to likelihood of conducting a test on LH surge day (2011).</p>
<h4>How is an ovulation calculator different to a fertility calendar?</h4>
<ul>
<li>An ovulation calculator estimates the likelihood of ovulation happening on a particular day.</li>
<li>A fertility calendar indicates the days when sex is likely to result in conception.</li>
</ul>
