What
is the Rule of Thumb?
If you
have an artificially high temperature put your thumb over
the temperature. Leave the temperature on your chart just
don’t use it to determine your coverline.
Coverline
and Rule of Thumb
Drawing
your coverline is easy. You will want to look for a rise of
at least .2 degrees F on your chart. Once you see this rise
in temperature you can draw your coverline. You normally count
six days back from the time you see this rise in temperature
to draw your coverline, but if you have a temperature that
is unusually high, put your thumb over this temperature and
then draw your coverline based on the six temperatures prior
to the rise.
How to
connect your temperatures
If you
have a temperature that is out of the ordinary and you decide
to apply the rule of thumb, you will not want to use this
temperature when you are connecting the temperatures on your
chart. Instead of drawing a line between each temperature,
like you normally do, draw a dotted line between the two temperatures
on either side of your “rule of thumb” temperature.
If I
oversleep should I adjust the temperature or use the Rule
of Thumb?
Some women
adjust their temperature when they oversleep. Generally, waking
temperatures rise about 1/10 of a degree for
every half hour you sleep in. You can adjust your temperature
but it may make your chart inaccurate. It is safer to apply
the Rule of Thumb if you have an unusual temperature.
