Tracking which type of body temperature is used to predict ovulation?

Basal body temperature tracking uses the body's temperature at rest, measured first thing in the morning before activity. Because ovulation causes a rise in progesterone, a slight uptick in basal temperature occurs after ovulation, typically about 0.4–0.8°F (0.2–0.4°C). This creates a biphasic pattern: lower temps before ovulation and higher temps after. By charting this daily over several cycles, you can confirm that ovulation has occurred and, when combined with other signs like cervical mucus, estimate the fertile window. This method relies on measuring at rest; temperatures taken orally, rectally, or as core body temperature are not used for this purpose because they reflect broader body temperature changes, not the subtle hormonal shift linked to ovulation.
