It is normal to have a discharge when you are pregnant and the discharge will increase significantly because after pregnancy, due to the increase in hormone levels, the discharge in the cervix and vagina will increase significantly from the original level. However, this discharge is milky white and has no odor or uncomfortable sensation. If the vaginal discharge is yellow in color, more voluminous, smelly or itchy, you may have vaginitis and must go to the hospital for treatment. If you have vaginitis in early pregnancy, it can have a significant effect on your pregnancy, sometimes leading to preterm miscarriage and sometimes stopping the development of the embryo.
