During pregnancy, the level of hormones in the body increases dramatically, especially estrogen and progesterone, which causes more vaginal shedding cells, and if you don’t take care of your personal hygiene, the vagina will have a fishy smell. This is the time to go to the obstetrics and gynecology department and have the vaginal discharge examined to determine which level of inflammation the vaginal discharge is and which type of vaginitis it is. As long as you know which kind of vaginitis you have, you can take the right medication, especially during pregnancy, so that you can take the right medication to avoid adverse reactions. It is possible to use medication during pregnancy, but local medication will not affect the health and development of the fetus, but it is important to treat it actively so that it does not cause upstream infections during labor, which may affect the birth.
