You should not douche the inside of your vagina when you are pregnant. There are a lot of bacteria in the vagina, and these bacteria keep each other in balance. Douching can flush out these bacteria, so the bacteria will be out of balance and the pathogenic bacteria will multiply, making it easy to get vaginitis. Pregnant women and normal women should not douche their vaginas. If they have vaginal inflammation, they can be treated with medication based on the results of the leucorrhea test. After the medication, you can place probiotics, or lactobacillus, in the vagina. When lactobacillus reproduces normally, the vaginal flora will return to normal and the vaginitis will be cured.
