Vaginal secretions increase after pregnancy, mainly due to changes in estrogen and progesterone, which increase local cervical secretions and vaginal secretions, and the leukorrhea will increase. The secretion itself is made up of shed cells and vaginal secretions, forming the leukorrhea. During pregnancy, it is important to keep the vulva clean, not to use pads to care for it or sanitary napkins, so as not to cause poor local ventilation, leading to the possibility of pathogenic bacterial infection caused by inflammation of the reproductive tract. For the phenomenon of increased vaginal discharge, it is recommended to wash the vulva with water 1-2 times a day, and change underwear diligently.
