Leukorrhea will be more before menstruation. Normal vaginal secretions are influenced by ovarian hormones and can appear to increase around the time of menstruation. If the leucorrhea is normal in color and has no odor, no treatment is needed and good hygiene and cleanliness is sufficient. The physiological increase of leucorrhea in women during ovulation or before menstruation is mainly due to the high level of estrogen and progesterone during this time, which causes an increase in leucorrhea due to the secretion of the female reproductive tract glands, which is a normal physiological phenomenon and does not require treatment. The normal leucorrhea is colorless and odorless, but if the leucorrhea increases, accompanied by odor, color change and vulvar itching, it may be due to gynecological inflammation, such as vaginitis, cervicitis, etc., you need to go to the hospital for routine leucorrhea examination to clarify the cause and then carry out targeted treatment. Women should pay attention to personal hygiene, bathe regularly, change underwear regularly, especially pay attention to menstrual hygiene, change sanitary napkins regularly, pay attention to abdominal warmth, avoid contact with cold water, and reduce the intake of spicy and stimulating food.
