In early pregnancy, normal vaginal discharge is usually clear or milky white, thin or slightly creamy, mild-smelling, and may increase in amount due to hormonal changes, while it should not cause itching or discomfort. Discharge that is yellow, green, gray, brown, very thick, foul-smelling, or accompanied by itching, burning, pain, or irritation may indicate infection or another issue that needs attention. You should consult a doctor if you notice unusual color changes, strong odor, discomfort, fever, or any bleeding with cramps, especially in early pregnancy, to ensure everything is normal and safe.
