least four hours of sleep and prior to any physical activity, eating, or drinking, etc. During the first
two weeks or so of your menstrual cycle, your BBT remains lower. Just after ovulation, the
increased production of progesterone causes your BBT to increase and this change will typically
last through the duration of the menstrual cycle. By monitoring when this temperature change
occurs, you can determine when ovulation has taken place. In the adjacent graphs, the low phase
refers to before and during ovulation. The high phase refers to your basal temperature rise after
ovulation.

The ibasal cannot store temperature readings lower than 93.2 degrees
Fahrenheit. You will hear an error beep intermittently. Press the Start button
to retake your measurement.
When the temperature is lower than the average
temperature, the low phase bar in the graph will blink (left
image). When the temperature is higher than average,
both the low and high phase bars will blink (right image).
When you do not save your
temperature, both the low
and high bars will blink
alternately.
