Ovulation Marker #1 – Tracking your BBT
Tracking your basal body temperature, abbreviated as BBT, is one of the main, and most common ways to track ovulation.
Taking your BBT, involves taking your temperature at roughly the same time every morning before getting out of bed. This includes logging your results, either by paper chart, or one of the handy apps you can download on your phone, to keep track of daily measurements and patterns
How to track your BBT
In order to do so, you will need a thermometer that goes to 2 decimal points, for example 36.68C or 97.68F. This makes it easier to notice temperature shifts, which is what you are looking for.
After ovulation, a hormone called progesterone, is released from the same follicle that the egg came from. This release of progesterone creates a slight temperature increase in the body. This is how we know ovulation has occurred, by tracking BBT.
For example, if you are taking your temperature throughout your entire cycle (which is required to get an accurate reading) your temperature will be lower for the first half, and higher for the second half.
Understanding your menstrual cycle
If you are unsure about the different phases of the menstrual cycle, their duration and what’s happening, I encourage you to go back and read the previous posts:
If a person has, say, a 28 day cycle (let me clarify though, a ‘normal’ cycle is anything between 21-35 days) from day 1 (first day of bleed) to day 14 (ovulation), body temperature would be roughly 2 tenths of a degree cooler than from day 15 to when bleeding starts again.
*If pregnancy occurs, progesterone levels continue to rise (throughout pregnancy) and therefor body temperature continues to rise and will not drop again at day 28.
You can purchase a BBT at any drug store, or easily off amazon. While you can get more fancy versions, it is not necessary, and you can easily get started with a thermometer for $20.
Apps to use when you start tracking your BBT
Some apps to check out are:
- Natural Cycles
- Period Tracker
It is important to remember, that in order to get accurate readings, you must take your temperature after 5 hours of uninterrupted sleep, at roughly the same time every morning, and certain things like drinking alcohol, staying up late, or illness will effect your body temperature.
