Preparing to conceive, how does a woman's body temperature change within a month?

Patient's question:

No

Doctor's answer:

After menstruation, the body temperature remains at a lower level (36.2—36.5℃). During the ovulation period, women experience changes in both basal body temperature and cervical mucus. Ovulation can be determined by measuring basal body temperature. During ovulation, the body temperature slightly drops first, then rises abruptly after ovulation, about 0.5℃ higher than before ovulation, and remains around 36.8℃ for a while. This pattern of temperature fluctuation—first low, then high—indicates that ovulation has arrived.
