There is no color judgment during or even after ovulation, except that during ovulation there will be excessive stimulation of the mucous membrane of the vagina due to estrogen in the body, causing stretched leucorrhea, which will last for 2-3 days. At a later stage, the leucorrhea may slowly increase due to the progesterone becoming more abundant. There may even be some women who have a small amount of brown discharge during ovulation, which can cause a small amount of bleeding due to the stimulation of the endometrium during the peak of estrogen, but such a situation cannot be intercourse. If a simple bleeding occurs once, it is physiological and will not affect the health. If it is very frequent, it should be treated, because the inability to have intercourse will affect conception, and early treatment and therapy must be carried out to avoid infertility.
