One very popular method of determining your fertile times of the month is the Basal Body Temperature (BBT) method. Specifically, your BBT is the temperature you have first thing in the morning when you are freshly awakened from three to five hours sleep. Ideally, you will take this reading before you get out of bed or engage in any activity beyond shutting off your alarm clock, and write it down in a chart.
Over time, the chart you keep will show you how your BBT changes throughout the month. Prior to ovulation, estrogen is the primary hormone flowing through your body. However, when ovulation occurs, your body experiences a surge of progesterone, which increases your body temperature. In the big picture, this should mean that your BBT is at its lowest point just prior to ovulation, and will increase approximately half a degree once ovulation occurs.
Unfortunately, while a BBT chart does tell you when you have ovulated, it will not necessarily help you predict your future ovulation with accuracy. In fact, studies show that using the BBT method alone achieves accurate results only about 75% of the time. Truly, a BBT chart serves as a good indicator of ovulation only if you are someone with a “perfect” 28 day cycle. For the majority of women, such a cycle may as well be a myth.
