The white fluid that comes out of the vagina during pregnancy is called leukorrhea, which shows an increase in leukorrhea after pregnancy due to the growth of estrogen and progesterone. Leukorrhea is usually a thick, white, clear fluid that does not have an odor and is more frequent than usual during pregnancy. The leukorrhea has the function of inhibiting the growth of bacteria. During pregnancy, you should try to pay attention to hygiene, pay attention to washing, and keep your pubic area dry and clean. If there is an increase in leukorrhea and you don’t pay attention to washing, it will accumulate in the vagina or vulva and cause bacterial infection and vaginitis. So you should pay attention to wear loose, cotton underwear, which is good for ventilation and can keep your pubic area clean and dry.
