Abundant vaginal discharge is common in pregnancy and is due to increased blood flow to the tissues inside your vagina, which discharges fluid more easily. The discharge is usually milky white and has no particular smell. However, itching, burning or a strong odor may be a sign of infection. If you have any such symptoms, contact your health care provider.
