When you are pregnant, your body may have a high level of estrogen and progesterone due to a decrease in resistance, which may cause abnormal leucorrhea due to an imbalance in the vaginal flora environment, and thus you may have leucorrhea odor. If the odor persists, vaginitis may be present. It is recommended to go to the hospital and register with the obstetrics department for a leukorrhea discharge examination to determine which type of infection the discharge belongs to, and vaginal plugs can be administered according to the situation. Because there are different distinctions of abnormal vaginal leucorrhea, such as the presence of mycotic vaginitis, trichomoniasis and bacterial vaginitis, and there may even be mild inflammation, the choice of medication differs for different inflammatory conditions to avoid side effects from the wrong medication, so it is important to have an examination to know which medication to use. It is not absolutely impossible to use medication during pregnancy, but only medication that has no effect on the fetus.
