I am having a milky, white, odorless vaginal discharge. its not burning or itchy. what could this be?

Normal: It may be normal most likely. If it is something new, please discuss with your doctor. In addition, I see that you are pregnant. Pregnant women have more discharge than non pregnant women. As long as it is not watery in consistency you should be fine

Exam and testing: Vaginal discharge requires an examination to determine the cause and treatment. Bacterial vaginosis is the most common cause and often has a vaginal odor. Vaginal itching can be a sign of a yeast infection. Sometimes vaginal discharge can be a sign of a sexual transmitted infection. Testing is important to determine the treatment and keep you and your partner safe.
