The increase in leucorrhea after pregnancy is actually a normal phenomenon, which is due to the increase in the level of estrogen after pregnancy and the corresponding increase in vaginal secretions. However, this secretion is milky white, and there is no odor, and no uncomfortable feeling. However, if the amount of leucorrhea flowing after pregnancy is particularly high, yellowish in color, with an odor and vulvar itching, you have vaginitis and must go to the hospital as soon as possible for treatment.
