In the week before the onset of menstruation, women tend to experience an increase in leukorrhea, which can be observed if it is not accompanied by itching, discomfort or foul-smelling discharge.
In the week before the onset of menstruation, that is, 15~28 days of the menstrual cycle, under the action of estrogen and progesterone, the secretion of female glands will be more vigorous, and the phenomenon of increased leukorrhea will occur.
In addition, as the level of estrogen in the body gradually increases before the onset of menstruation, the cervical canal will also secrete more mucus under the action of estrogen, increasing the amount of leukorrhea.
Normally, leukorrhea increases in women in the week before the onset of menstruation, and the increased leukorrhea is often thicker and similar to yogurt, but has no particular odor. If there is an increase in leukorrhea, but with a smell, or a change in the color of the leukorrhea, you need to be alert to the occurrence of vaginal or cervical diseases, and you can go to the hospital in time.
