What is the most accurate way to measure ovulation?

1. Basal body temperature method

The basal body temperature method records changes in your own body temperature by measuring your body temperature through the mouth or anus. During the measurement period, the body temperature usually rises by about 0.3-0.5 degrees Celsius and then remains stable. This method can accurately measure a woman's ovulation period because it can record obvious changes in body temperature and can accurately predict body temperature changes in the next few days.

2. Calendar method

The calendar method predicts a woman's ovulation period by observing her menstrual cycle and the dates on the calendar. A woman's menstrual cycle usually lasts 28 days, but it may be longer or shorter in some women. By observing a woman's menstrual cycle and the dates on the calendar, you can predict when the best time to get pregnant will be.

3. Test paper method

The test strip method predicts a woman's ovulation period by testing hormone levels in urine.
