Moreover, the formation of menstruation is also related to the secretion of estrogen and progesterone, the thickness of the uterine lining, and the development of follicles. Therefore, it is not possible to judge the time of menstruation by the time of the appearance of leukorrhea, the two are not necessarily related to each other, and are related to a variety of factors. As you can see, the appearance of leukorrhea in an 11-year-old girl does not indicate that she is about to have her period. Parents should remind their children to pay attention to personal hygiene, such as washing and changing underwear, when they have leukorrhea.
