Basal body temperature(Bbt or BTP) is the lowest body temperature
attained during rest(usually during sleep).
You shouldn't measure the Bbt using the armpit method because it won't be accurate.
Others who practice Bbt believe that it helps to raise your carbon dioxide levels.
The Bbt tracking data collected during this time will
help determine ovulation and reveal hormonal disorders(if any).
This is contrary to the fluctuations in the basal body temperature(Bbt) which occurs mostly after ovulation.
For example, higher levels of oestrogen present during the pre-ovulatory(follicular)
phase of the menstrual cycle will lower your Bbt.
The best way to measure ovulation
is by using a Basal Body Temperature(Bbt) Thermometer which monitors your cycle by indicating
small fluctuations in body temperature.
Since the life
span of the egg is only one day, when using the Bbt method there may be very less
time left to conceive.
Women can detect these problems on their own by ovulation predictor kits,
basal body temperature(Bbt) charts,
as well as using blood tests that reveal hormone levels.
If you didn't get pregnant this cycle, your Bbt should drop 10-14 days after ovulation, around
the time your next period is supposed to start.
If you have been charting your Bbt to determine when you ovulate, its
continued elevation for more than two weeks may mean you are pregnant.
Write down your temperature each morning on a piece of graph paper or a Bbt chart, which is a pre-made graph on which you can plot your temperature.
