Many women become anxious about vaginal discharge during pregnancy but usually the discharge may be considered normal if it is odorless, thin in consistency and white in color. However, vaginal discharge that is yellowish or greenish in color, looks like cottage cheese or has an unpleasant smell may indicate an infection, especially if accompanied by vaginal itching. A blood stained or brownish discharge may be a cause for concern too and needs to be brought to the doctor’s notice.
