What Is a 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 can be taken at the same time every morning when you first awake.

Why Is BBT Charting Helpful?
Charting your basal temperature is helpful in determining whether and when ovulation occurs. Ovulation is the release of an egg (ovum) from the ovary and ordinarily happens only ONCE in each menstrual cycle. Conception can take place only if intercourse takes place at or near this time, during the interval of transition between low and high temperatures.

By carefully recording your basal temperature when you first awaken, you will begin to notice a pattern of temperature fluctuation in your monthly cycle. The slight increase in basal temperature is an indication of ovulation or fertility by which you can regulate a pattern on activity to either achieve conception or avoid pregnancy.

Commonly Asked Questions about the Mabis Digital Basal Thermometer

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.
