The white, sticky, snot-like discharge that appears under the vagina is leukorrhea. The normal leukorrhea is white and sticky, but the clear, snot-like leukorrhea is considered to be the leukorrhea of ovulation. During ovulation, due to the change of sex hormones in the body, the leucorrhea becomes transparent and lacrimal, with a snot-like appearance and more than usual amount of secretion. After ovulation, the leukorrhea will slowly return to normal, with an increase in viscosity and opacity. As long as the leukorrhea does not have a distinct fishy smell or is accompanied by obvious vulvar and vaginal itching, it is normal. The female leucorrhea is made up of fluid and shed cells secreted from the endometrium, cervix and vagina under the influence of estrogen in the body, and the presence of gynecological inflammation can be determined based on the results of the leucorrhea test. It is advisable to pay attention to perineal hygiene, to enhance cleaning on days when there is a lot of leucorrhea secretion, and to change underwear regularly.
