If the temperature does not rise during ovulation, it does not necessarily mean ovulation. Although a woman's body temperature will rise during ovulation, it does not necessarily mean that she is ovulating. In fact, a woman's ovulation time is affected by many factors, including menstrual cycle, hormone levels in the body, physical condition and environmental factors.

In a woman's menstrual cycle, ovulation is an important physiological process. During the ovulation period, a woman’s egg matures and is expelled from the ovary. It is then ingested by the fallopian tube and enters the fallopian tube to wait for fertilization. Generally speaking, women begin to measure basal body temperature on the 14th day of the menstrual cycle, and reach the highest body temperature level between the 16th and 20th days, and then begin to decrease. This is when a woman ovulates.

However, not all women experience a rise in temperature during ovulation. This may depend on a variety of factors, including a woman's health, menstrual cycle, and hormonal levels. In addition, women's bodies are also affected by environmental factors, such as temperature and humidity.

Therefore, although the lack of temperature rise during ovulation does not necessarily mean that a woman is not ovulating, if she wants to accurately predict her ovulation time, it is recommended that women consult a doctor or a professional medical institution. Doctors can help women accurately predict when they will ovulate by measuring basal body temperature, observing menstrual cycles, and conducting other tests.
