It is usually estimated by a temperature measurement immediately after awakening and before any physical activity has been undertaken. This will lead to a somewhat higher value than the true BBT. In women, ovulation causes a sustained increase of at least 0.2 °C (0.4 °F) in BBT. Monitoring BBTs is one way of estimating the day of ovulation.
The true BBT can only be obtained by continuous temperature monitoring through internally worn temperature sensors. In women, ovulation will trigger a rise in BBT between 0.2º and 0.5 °C. (0.5 and 1.°F) that lasts approximately until the next menstruation. This temperature shift may be used to determine the onset of post-ovulatory infertility.
However, fertility awareness is usually used as a broad term that includes tracking basal body temperature and cervical mucus as well as cycle length. The World Health Organization considers the rhythm method to be a specific type of calendar-based method, and calendar-based methods to be only one form of fertility awareness. [2]
A basal body temperature (BBT) thermometer is often used by women to chart their basal body temperature chart and hence to predict their fertile period or ovulation. A basal thermometer is more reliable and accurate than a simple glass thermometer since glass thermometers are only accurate to .2 degrees Fahrenheit whereas a basal thermometer is ...
The three primary signs of a woman's fertility are her basal body temperature (BBT), her cervical mucus, and her cervical position. [54] Computerized fertility monitors, such as Lady-Comp, may track basal body temperatures, hormonal levels in urine, changes in electrical resistance of a woman's saliva, or a mixture of these symptoms.

Ovulation occurs ~35 hours after the beginning of the LH surge or ~10 hours following the LH surge. Several days after ovulation, the increasing amount of estrogen produced by the corpus luteum may cause one or two days of fertile cervical mucus, lower basal body temperatures, or both. This is known as a "secondary estrogen surge".
Basal body temperature changes during the menstrual cycle. Higher levels of progesterone released during the menstrual cycle causes an abrupt increase in basal body temperature by 0.5 °C to 1 °C at the time of ovulation. [7] This enables identification of the fertile window through the use of commercial thermometers.
This model, like the Billings ovulation method, is based on observations of cervical mucus to track fertility. Creighton can be used for both avoiding pregnancy and achieving pregnancy. Creighton can be used for both avoiding pregnancy and achieving pregnancy.
