How to calculate ovulation?

Although calculation methods vary, here are some common ones:

1. Measure basal body temperature: Measuring basal body temperature can help calculate ovulation. Take your oral temperature every morning when you wake up and record the value. Generally speaking, a woman's body temperature will fluctuate within this range during the menstrual cycle, that is, the body temperature will rise by about 0.3-0.5 degrees Celsius, which will last until the next menstruation.

2. Observe the menstrual cycle: Observing the menstrual cycle can help determine the ovulation period. Generally speaking, the length of a woman's menstrual cycle affects when she ovulates, and women with shorter cycles may need to be measured and observed more frequently.

3. Use David test strips: David test strips are a commonly used method of measuring ovulation. The method of use is to insert the test strip into the urine, hold it for 2-3 minutes, and then observe the result. Typically, the test strip will show two lines, one of which may be deeper than the other, indicating that ovulation has been missed.

4. Calculating the calendar: For calendar lovers, calculating the calendar can help determine your ovulation period. Mark the time of your next period on your calendar and take measurements and observations a few days before and after this date.

None of these methods are absolutely accurate, so it is recommended that women consult a doctor or professional health advisor when using these methods to ensure accuracy and safety.
