Yellowish leucorrhea during pregnancy is clinically abnormal. During pregnancy, the increase in estrogen in the body leads to an increase in vaginal discharge, but the discharge is still milky white with no odor or a faint fishy smell. If the leukorrhea appears yellow, the most common clinical cause is vaginal inflammation. It is recommended to keep the vulva clean during pregnancy, wash it with warm water 1-2 times a day and change underwear regularly. If necessary, you can go to the hospital to take a routine test of the leukorrhea and give the necessary treatment according to the results. During pregnancy, especially in the early stages of pregnancy, if there is vaginal inflammation, vaginal plugs are often not allowed, but only to keep the vulva clean. For example, if the vaginal inflammation is caused by a bacterial infection, oral cefuroxime tablets can be used for treatment.
