Leucorrhea usually turns yellow during ovulation, which is a normal physiological phenomenon. During ovulation, women’s vaginal secretions will increase, which contain a large number of white blood cells and proteins. These components can help women reproduce better. However, if a woman's discharge becomes unusually yellow, it may mean that she is experiencing some kind of health problem.

In addition to the ovulation period, the color of a woman's discharge may also change due to individual differences, frequency of sexual intercourse, vaginal cleanliness and other factors. Therefore, if a woman encounters any difficulty in observing discharge, or feels discomfort, it is recommended that she consult a doctor for more accurate diagnosis and treatment recommendations.

In summary, yellow discharge during ovulation is a normal physiological phenomenon, but if it is accompanied by other symptoms, then women should seek medical attention promptly to rule out any underlying health problems.
