Leucorrhea is a kind of fluid in the female body, which is composed of proteins, carbohydrates and fats. During ovulation, a woman’s leucorrhea will become clearer, more transparent, and abundant. This phenomenon is called the “zona pellucida phenomenon.”

Therefore, if you want to predict your ovulation period, you can infer it by observing the appearance time of the zona pellucida phenomenon. Usually, within three days after the appearance of the zona pellucida phenomenon, a woman's eggs will mature and be discharged, so this is the best time to get pregnant.

It is important to note, however, that the zone pellucida phenomenon is not the only prediction method. Women can also predict ovulation by looking at indicators such as their menstrual cycle, body temperature and hormone levels. If you are interested in predicting ovulation, it is recommended to consult a doctor or professional doctor to obtain a more accurate prediction method.
