Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? What is the method for measuring body temperature to track ovulation?Doctor's answer:
Menstrual cycles are regular, with each cycle lasting 28-30 days. Ovulation generally occurs around 14 days before the next menstrual period. The 10-day period between 5 days before ovulation and 4 days after ovulation is the fertile window.The method for measuring basal body temperature is as follows: Measure your temperature with an oral thermometer immediately after waking up each morning, without getting out of bed. It is best to do this at the same time and in the same position every day.
Generally, a woman's basal body temperature remains around 36.5°C before ovulation. During ovulation, the temperature slightly drops by about 0.2°C. After ovulation, it rises to around 37°C and remains at this level until the next menstrual period, then returns to the original temperature level.
If you measure your basal body temperature for three menstrual cycles, you can accurately predict your ovulation date. Additionally, record the daily temperature readings in a table to monitor any changes in your temperature.
