The discharge on the underwear every day may be the normal secretion from the uterine glands and cervix, as well as the vagina, or it may be due to vaginitis, cervicitis, endometritis, adnexitis, pelvic inflammatory disease and other pathological phenomena. If there is only white or milky white secretion on the underwear every day, without symptoms such as vulvar itching and odor, it means that it is normal secretion, which is a normal physiological phenomenon and does not need special treatment. Pay attention to good vulvar hygiene, change underwear frequently. If there is yellow or purulent discharge on the underwear every day, and some women also have symptoms such as vulvar itching, which is a pathological phenomenon, you need to consult a gynecologist, cooperate with the doctor to do gynecological and leucorrhoeal examinations, and then confirm the diagnosis of the symptomatic drug treatment. If there is a coffee-colored discharge, it may be ovulation bleeding and does not require special treatment.
