How To Chart Your Basal Body Temperature (BBT)
Here’s what you need to do to accurately chart your BBT.
First, if you don’t already have a basal body temperature thermometer, get yourself one. You can get one at your local pharmacy or even
order it online. The box or package that you find the thermometer in will say basal or fertility thermometer. Once you have your BBT thermometer there are a few simple guidelines to follow to get an accurate reading.
The closer you get to these ideals, the more reliable your chart will be.
- Take your temperature when you first wake up. It should be the first thing you do when you open your eyes and stay resting while you take it.
- Take your temperature at the same time each morning or as close to it as you possibly can. You can set an alarm if needed. It’s
important to note the time your temperature was taken.
- Try to take your temperature after a solid good nights sleep. Choose a regular time when you’re likely to have been sleeping for a few hours.
- Finally, take your temperature the same way every day. Most women prefer to take it orally but vaginally is also okay. Just be consistent.
These are the basics to get a reliable BBT measurement. If you miss a day or two or you don’t have ideal conditions from time to time, your BBT chart reading can usually still interpret your pattern but it’s best to follow the guidelines as close as you can for the most accuracy. We recommend that you enter your BBT as soon as you take it and with this data you can pinpoint your ovulation date, evaluate your conception chances and provide a reasonable date to test for pregnancy along with other insights about your cycle.
