Take your temperature before rising in
the morning as any activity can raise your BBT.
Take your temperature at the same time
Take your temperature after at least 3
consecutive hours of sleep
Keep your thermometer accessible from
your bed so you do not have to get
up to get it.
Use the same thermometer throughout your
cycle if possible.
Keep a spare thermometer in case one
breaks (especially if you are using a glass thermometer).
Temperatures can be taken orally (recommended) or
vaginally but must be taken in the same place throughout the
cycle since the temperatures of the different parts may vary.
Most women prefer to take their temperatures orally and this
is usually fine, though some women find that they get a
clearer reading by temping vaginally.
Record your temperature soon after you
take it (or ask your partner to) since most thermometers only
store a reading until the next use. If you have to do
something else or want to stay in bed, you can record it
If you must use a heating pad or electric
blanket, keep it at the same setting throughout your cycle.
Make a note of its use.
Take your temperature before doing
anything else including eating, drinking or going to the
bathroom. If circumstances arise that prevent you from taking
your temperature right away, take it as soon as you are able
and make a note of the circumstances.
Start your chart from the beginning of
your cycle, i.e. when you start bleeding.
