There is secretion in pregnancy, and the secretion is increased compared with non-pregnancy. After pregnancy, the level of estrogen and progesterone in the body increases, which makes the glandular secretion in the reproductive tract flourish. After pregnancy, the blood flow in the reproductive organs is richer and the glandular secretion function is enhanced, which makes the secretion increase, and the color of the secretion is white or milky white, without odor and without vulvar itching symptoms. Pregnant women should wear loose, breathable and cotton underwear, wash their vulva every day and keep it clean and dry to reduce the chances of vaginitis. If there is an increase in discharge, odor or vulvar itching, see a doctor promptly.
