Here’s how to check your menstrual ovulation period:

As the menstrual cycle progresses, a woman's body gradually adapts to the new hormone levels. Later in the menstrual cycle, hormone levels in women reach their peak, which may cause some pain or discomfort, especially at night or early in the morning.

At this time, women with regular menstrual cycles can use the following methods to estimate their menstrual ovulation period:

1. Observe symptoms: Some women can predict their menstrual ovulation period by observing symptoms. For example, they may experience some mood swings, a slight fever, or a slight feeling of hunger. These symptoms usually appear around the time of menstruation and ovulation.

2. Measure body temperature: Women can estimate their menstrual ovulation period by measuring body temperature. Before menstruation and ovulation, a woman's body temperature is usually lower than normal, and after menstruation and ovulation, the body temperature will rise to normal levels.

3. Use David test strips: David test strips are test strips that can test a woman’s menstrual ovulation period. The method of use is very simple, just insert the test strip into the vagina and wait 2-3 minutes to observe the result.

The above method is not guaranteed to be 100% accurate because everyone's menstrual cycle is different. Therefore, if you are not sure about your ovulation period, it is best to consult your doctor or professional health care consultant.
