Vaginal discharge is a term given to fluids expelled from the vagina or staying inside the vagina. Vaginal discharge can have different colors like clear, white, yellow, brown, or green, and it can be odorless or have odors.
Most vaginal discharge is normal and can reflect the various stages of the condition of the vagina during the menstrual cycle. Some vaginal discharge however, especially if it has an odor or an abnormal color can be a result of an infection, such as asexually transmitted disease and must be further investigated.
Pregnant women often report an increase in vaginal discharge, and white, milky vaginal discharge is sometimes among the first early signs and symptoms of pregnancy that a woman observes and it's common to notice an increase in white, milky discharge early in pregnancy. The typical pregnancy vaginal discharge is normal and often referred to as leukorrhea, or "white flow." Leukorrhea is typically odorless or has only a mild odor and generally milky white in appearance. If you notice an increase in this whitish discharge and there is a possibility that you might be pregnant, take a home pregnancy test. Discharge is typically normal when colorless and odorless, and has been reported by many women as a sign of early pregnancy.
Aside from the "normal" leukorrhea associated with pregnancy, however, there are other possible reasons for vaginal discharge. Some of these reasons are normal, while others may require further diagnostic tests and treatment. As long as the vaginal discharge you are experiencing has no odor, and is not accompanied by burning or itching, it may be an early pregnancy sign. However, if your vaginal discharge is foul-smelling, itchy, and/or is a color other than clear or milky white, you should see your gynecologist immediately. Your doctor will need to examine you because you could have a viral or bacterial infection or a sexually transmitted disease that must be treated.

Vaginal discharge could also be observed as an indicator of ovulation. If you typically pay attention to how much discharge you usually have throughout the month, you may not have any trouble noticing an increase in vaginal secretions, and this could be your first indicator that you might be pregnant.
Not every woman experiences this type of vaginal discharge, so not seeing the discharge does not mean that you aren't pregnant. Not all women experience the same pregnancy symptoms; you could be pregnant and not have this particular early symptom. The surest way to determine whether you are pregnant is to see your doctor for a pregnancy test.
