Leucorrhea during ovulation is a liquid secreted by a woman's body during her menstrual cycle, usually colorless or light yellow. It is one of the special periods in women's menstrual cycle and one of the key periods for female fertility. So, how many days does leucorrhea last during ovulation?

So why does a woman’s vaginal discharge start to appear on day 14 of her menstrual cycle? This is primarily due to the interaction between a woman's menstrual cycle and her ovarian cycle. A woman's ovaries begin secreting eggs on day 14 of the menstrual cycle, and these eggs usually mature within a few days and enter the fallopian tubes.

Therefore, a woman's vaginal discharge begins on the 14th day of her menstrual cycle and increases over the next few days. This is also a good time for women to have sex because this is when the egg cells can enter the fallopian tubes and await fertilization.

Although vaginal discharge begins on day 14 of a woman's menstrual cycle, it usually lasts for several days and varies from person to person. Generally speaking, a woman's vaginal discharge on the 14th day of her menstrual cycle may last for about 3-5 days. Therefore, women should pay close attention to their body changes and have sex at this time to ensure that they obtain healthy egg cells.
