It is not uncommon for pregnant women to experience changes in vaginal discharge, including an increase in amount and changes in consistency and odor. A white, thick discharge with a strong smell can be normal during early pregnancy due to hormonal changes and increased blood flow to the vaginal area. However, if you are experiencing any itching, burning, or discomfort along with the discharge, it is important to consult your healthcare provider as it could indicate an infection. Since you mentioned that you had swabs done at the doctor's office before discovering your pregnancy and they came back normal, it is reassuring that there were no signs of infection at that time. However, if you are still concerned about the odor or any other symptoms you are experiencing, it is always best to reach out to your healthcare provider for further evaluation and guidance. They can provide personalized advice based on your specific situation and medical history.
