If you have a yellow vaginal discharge after pregnancy, it is not normal. Normally, vaginal discharge increases after pregnancy, but it is milky white, without odor and does not cause itching of the vulva. If the vaginal discharge is yellow, it indicates an inflammatory reaction of the vaginal mucosa or a chronic inflammation of the cervix. While examining the leukorrhea, gently open the vagina with a speculum to see if there is localized congestion, edema and purulent discharge from the cervix, so as to rule out vaginal inflammation and inflammation of the cervix. If there is inflammation, active treatment must be given to avoid the invasion of inflammation into the uterine cavity which can cause intrauterine infection and affect the normal development of the embryo.
