A normal woman has leukorrhea in her vagina, which is colorless, transparent or a white paste with a slightly sour odor. When the estrogen level in the body increases after pregnancy, the amount of leukorrhea will gradually increase, but the color will not usually change. The yellowing of the leucorrhea in the seventh month of pregnancy may be due to the high level of estrogen in the body during pregnancy and the poor resistance of the body, which may induce vaginal inflammation, which may cause congestion, edema and itching in the vulva. It is recommended that women should have a gynecological examination and a routine white belt test to rule out the possibility of vaginitis. The above content is for reference only.
