A clear discharge in an eleven and a half year old girl indicates the presence of leukorrhea, but it is not a symptom that can be used to determine when menstruation is due.
In general, the age of the first menstruation of girls is about 12 to 16 years old, when ovarian function matures, there will be estrogen secretion in the body, when the endometrium grows to a certain extent under the action of estrogen, it will produce shedding, so that menstruation comes. The symptom of leukorrhea alone does not clearly determine the exact time of a girl’s menstruation, which varies from person to person.
It is recommended that girls who are not menstruating learn something about taking care of themselves after menstruation in order to prepare for the first menstrual period and promote good health. If a girl’s leukorrhea has an abnormal color or smell, she may have an infection and should seek medical attention.
