For some women, knowing their menstrual cycle and ovulation is very important. If you are a woman who gets her period on the 17th, then your menstrual cycle is 28 days, and your ovulation period will usually be between the 14th and 23rd of each month.

The method of measuring body temperature is very simple. You only need to measure your body temperature when you wake up every morning. Typically, a woman's body temperature will vary based on her daily basal body temperature (that is, her body temperature when she wakes up in the morning). Generally speaking, a woman's body temperature will rise by 0.3 to 0.5 degrees Celsius during ovulation. Therefore, you can judge your ovulation period by observing changes in body temperature.

In addition to measuring your temperature, you can also use other methods to calculate your ovulation period. For example, you can use a calendar or calculator to track your menstrual cycle and ovulation, and use your cycle to deduce your ovulation date.

In general, it is very important to understand your menstrual cycle and ovulation period. This can help you better plan your diet, exercise and living habits, and better prepare for a healthy life.
