Leukorrhea like rice paste without odor is mostly seen before menstruation, because the level of progesterone in women’s body is higher at this time. Progesterone can make the secretion from the cervix sticky, and its role is to prevent bacteria and sperm from entering the uterine cavity. If there is no fishy smell in such a leucorrhea and there is no vulvar itching, then it is normal. Women must pay attention to the hygiene of the vulva because a warm, humid environment is most likely to make bacteria grow and multiply, so wash your vulva every night, change your shorts every day, and keep your vulva dry, and the symptoms will disappear after you have had a period.
