Increased egg-white-like discharge with a faint fishy odor is most likely due to ovulation, as the hormone levels in the body change during ovulation, causing the cervical discharge to become relatively thin, resulting in egg-white-like leucorrhea, which is particularly well stretched. If the vaginal discharge has a very fishy odor, it is not necessarily caused by ovulation, but by inflammation of the vagina, most commonly bacterial vaginosis caused by anaerobic bacterial infection. If there is a strong fishy odor, the possibility of cervical cancer or endometrial cancer should be ruled out, so go to the hospital as soon as possible and get the appropriate treatment according to the results. It is also recommended that women should have a gynecological examination once a year, mainly to rule out inflammation and the possibility of malignant tumors.
