Basal body temperature charting

Basal body temperature (BBT) charting may be recommended to evaluate your ovulation. Although BBT charting is not predictive of ovulation, it can be useful in confirming that ovulation has occurred in a particular cycle. This test is inexpensive, relatively convenient and non-invasive.

BBT charting is performed by taking the temperature immediately upon awakening each morning using a basal body thermometer. This thermometer is graduated in 0.1°, as opposed to 0.2° and can be found at any pharmacy or grocery store. After taking your temperature each morning, you should plot it on a graph that we will give to you. Your temperature will increase by about one degree after you have ovulated due to progesterone production. Therefore, do NOT wait until your temperature rises to have intercourse.
