The importance of your coverline is that it will allow you to know when you have ovulated. The coverline allows you a visual reference point for all changes with your basal body temperature. That’s why you will want to not only chart your basal body temperature each day, but also draw your coverline so that you know when you have ovulated and can predict the next month, and every month after, when your most fertile time might be. Drawing the coverline does seem a little confusing at first, however it is quite easy as long as you pay attention and follow directions. It’s all about locating your highest temperature during the previous six days once your temperature spikes 2/10s of a degree. The following will explain in more detail how to draw your coverline and its importance.

Drawing the Coverline

In order to draw your coverline you will need to be tracking your basal body temperature every single day. This means that every morning when you wake up you take your temperature with a basal thermometer before getting out of bed. It should be at almost the exact same time every single day for the most accurate readings. Now, when you see that your basal body temperature has risen 2/10s of a degree over the temperatures of the past six days then you know you have ovulated and are experiencing a thermal shift. What this means is that if your temperature has been in the 97.5 degree range for the past six days and then it shoots up to 97.7, a 2/10s of a degree increase, that you have ovulated and can now draw your coverline.

Look at the temperatures from the previous six days and find the highest one. It might not be significantly higher than any of the others, but they usually aren’t. Just find the highest one and then move up 1/10 of a degree to mark the coverline. So, if your highest temperature during the past six days was 97.57 then you will need to mark your coverline at 97.67 because that would be a 1/10 degree increase. Draw your coverline all the way across the entire chart. You will also want to highlight these six numbers.

Now that you have your coverline you will be able to anticipate when your most fertile time will be the next month.
