You and your partner are struggling to conceive so you have begun hanging out with your good buddy…Google.

What does that even mean??

These were my exact thoughts when I went through this process a few years ago so I know exactly what you are going through.

What is the definition of Basal Body Temperature?

Basal body temperature is the lowest temperature of a person’s body while at rest.

How Do You Find Your Basal Body Temperature?

The daunting and confusing title “Basal Body Temperature” makes it sound like it will be difficult to calculate and find, but it’s not! Great news, right? Unfortunately, the thermometer that I use to track my Basal Body Temperature is no longer on Amazon, but this thermometer is very similar and will get the job done right.

When taking your temperature, all you have to do is put it under your tongue as you would if you had a fever. So…no need to get cray and put it somewhere else…

There are a couple key things when taking your basal body temperature.

  • Take your basal body temperature at about the same time every day AND it needs to be in the morning. The general advice is that you should be taking your temperature BEFORE your feet hit the floor so you are still in a total state of relaxation.
  • Track it! It’s all fine and great that you are taking your temperature every day, but it’s just as important that you are keeping a record of your findings. The more you record, the faster you will learn your body’s temperature patterns. My very favorite app to record my temperatures is called OvaGraph. The reason it is my favorite is because it is extremely EASY to use! Of course, you can go out and get the apps with all the bells and whistles, but if you are looking for easy, this is the one! Tracking your temperature and analyzing the charts is NOT simple.

Why Is This So Important?

Tracking your temperature will help you learn more about your body. You may or may not know that as your body takes its course through your menstrual cycle, it goes through normal ups and downs in temperature. These temperature fluctuations point to crucial events in a cycle such as ovulation, implantation, and period. For example: Ovulation will generally cause an ever so slight increase (tenth or hundredth of a degree) in your temperature. Your temperature will continue to remain a little more elevated than it was during the Follicular Phase (between period and ovulation). If you are about to get a visit from Aunt Flow then your temperature will drop significantly (by 1-3 degrees). If you are pregnant, you will not see that drop, instead you will see your temperature continue to remain elevated.

These are the general rules of thumb, but of course not every body will follow this exact rule….most will. The holy bible of Basal Body Temperature is a book called Taking Charge of Your Fertility. I highly recommend this book. It includes informative graphs and examples of actual real-life scenarios. It goes into further detail about tracking, the importance of it, and ultimately…how to use it to help get you preggers.
