What Is Basal Body Temperature (BBT)?

Basal temperature is the lowest normal body temperature of a person immediately upon awakening in the morning - BEFORE you get up, move around, eat, drink, smoke, talk - if possible, while you are still "half asleep". The best reading of your basal temperature is taken at the same time every morning when you first awake.

Why Is BBT Charting Helpful?

Charting your basal body temperature is helpful in determining when and if ovulation occurs. Body temperature normally rises after ovulation due to hormonal changes. Thus, a temperature increase near the middle of your menstrual cycle can indicate ovulation has occurred. Charting your BBT can help you predict your most fertile period or ovulation in future months.  

By carefully recording your basal temperature each morning when you first awaken, you will begin to notice a pattern of temperature fluctuations in your monthly cycle. The slight increase in basal temperature is an indication of ovulation or high fertility.  

During the first two weeks of your cycle, your body temperature is lower (96.0-97.5 F).   During ovulation, a rise in body temperature takes place.   This is caused by an increase of the hormone progesterone – in order to provide a warmer, more fertile environment. A temperature rise of 0.4 to 0.6 degrees F can be detected by the basal thermometer. Then you will know when you are about to ovulate and can then choose to try to conceive or avoid pregnancy.

FAQ about Digital Basal Thermometers

My thermometer isn't telling me what my last temperature was.

In order to recall the last temperature taken, press and hold the on button until it appears. If you let go of the on button, the basal thermometer will then ready itself to take another temperature.

My basal thermometer is reading "Lo". Is my thermometer broken or is the battery running out?

When your thermometer shows "Lo", that is the indication that your basal thermometer is ready to use.
