Extraordinary leucorrhea does not necessarily mean ovulation, because women secrete different secretions at different times in the menstrual cycle. During ovulation, a woman's vaginal discharge will increase, which may include clear, white, and very fluid discharge, known as leucorrhea.

However, it is not appropriate to think that today is the ovulation period just because the amount of leucorrhea has increased. Because a woman's menstrual cycle is affected by many factors, such as physiological conditions, diet, medications, etc., it is not always accurate to determine the ovulation period.

If women want to determine the specific ovulation period, it is recommended that they observe their menstrual cycle, record changes in their secretions, or consult a doctor. Doctors can determine the specific ovulation period based on factors such as a woman's menstrual cycle, health status, and reproductive requirements.

In short, although increased leucorrhea is a criterion for determining ovulation, it is not always accurate. Women should determine the specific ovulation period based on their menstrual cycle and physical condition.
