Pathological mucus that occurs during late pregnancy does not always have a brown tint. Also, expectant mothers are faced with leukorrhea that has a greenish or yellow tint. Such vaginal secretion is a serious reason for an urgent visit to the antenatal clinic.
Quite often, yellow discharge during pregnancy in the third trimester indicates the presence of a sexually transmitted disease in the mother. For example, gonorrhea is expressed by the obvious yellowness of the sexual secretion. If the yellow color of the mucus is quickly replaced by a green tint, things are bad - this is a signal of an acute inflammatory reaction or the obvious presence of a dangerous infection in the female body.
