If there is yellow vaginal discharge during pregnancy, it is often the result of vaginal inflammation. In normal pregnancy, although the vaginal discharge is increased by estrogen, it is still creamy white in color and has no odor or a faint fishy smell, but it is not yellow in color. If the color is yellowish discharge, it is mostly due to local inflammation of the vagina. Therefore, it is better to go to the hospital to take vaginal discharge for a routine white belt test and treat the infection according to the pathogenic bacteria. After pregnancy, due to the increase of vaginal discharge, you should keep your vulva clean, wash it with warm water twice a day and change your underwear regularly. But don’t get into the habit of using pads, because pads can cause poor local ventilation and pathogenic bacteria to multiply.
