Both baths and showers are fine to take during pregnancy, but very hot baths, hot tubs, and saunas can be harmful to the fetus, or cause you to faint. You also might want to avoid taking frequent bubble baths or baths with perfumed products that might irritate your vaginal area, and increase your risk of a urinary tract infection or yeast infection. Do not use douches, even vinegar-based douches, without first talking with your health care provider. Although vaginal discharge tends to be heavier during pregnancy, you should see your health care provider if you have vaginal itching, burning or a heavy discharge. You could have a urinary tract infection, yeast infection, viral or bacterial infection that needs treatment.
