Increased discharge from the vulva accompanied by pain in the lower abdomen may be a sign that labor is imminent. If a woman simply has an increase in discharge, it may not be a sign of impending labor, but may be caused by inflammation of the vagina. Therefore, when a woman suffers from excessive discharge, she needs to go to the hospital in time for examination.
