Determining ovulation is one of the key steps in pregnancy. During the ovulation period, a woman’s secretion will increase and appear transparent, clear, and sticky. This secretion is called leucorrhea. By judging leucorrhea, we can better understand a woman's health and speculate on possible pregnancy chances.

So, how to observe and judge a woman’s ovulation period? Here's how:

1. Observe changes in secretions: During the ovulation period, women’s secretions will appear transparent, clear, and sticky. If women experience these symptoms during this period, it means they are about to ovulate.

2. Record menstrual cycle: If a woman has a regular menstrual cycle, she can record her menstrual cycle and observe changes in secretions. A few days after the cycle ends, a woman's discharge will increase again and become clearer, translucent, and thicker.

3. Measure body temperature: Women can determine their ovulation period by measuring body temperature. A woman's body temperature will rise in the days after her cycle ends and continue into the later stages of pregnancy.

4. Use a pregnancy test stick: If a woman is not sure whether she has entered the ovulation period, she can use a pregnancy test stick to judge. Pregnancy tests can detect pregnancy a few days after a woman's menstrual cycle ends.

To sum up, by observing changes in secretions, recording menstrual cycles, measuring body temperature, and using pregnancy tests, women can better judge their ovulation period and take appropriate measures to increase their chances of pregnancy.
