It is not uncommon for pregnant women to experience changes in their vaginal discharge. Increased levels of estrogen can cause an increase in vaginal secretions, which may appear thicker or have a different consistency than usual. However, if you are experiencing symptoms such as burning, itching, or an unusual odor along with the discharge, it could be a sign of a vaginal infection such as yeast infection or bacterial vaginosis. It is important to consult your healthcare provider to determine the cause of these symptoms and receive appropriate treatment if necessary. They will be able to assess your baby's health and provide guidance based on your specific situation.
