Yes, it is normal to experience breast leakage during pregnancy, even before milk production begins. The fluid you are experiencing is called colostrum, which is a precursor to breast milk. Colostrum is rich in antibodies and nutrients that provide essential support to the baby's immune system after birth. It is common for women to start producing colostrum as early as the second trimester of pregnancy. The amount and timing of colostrum production can vary from woman to woman. If you have concerns about the color or consistency of the fluid, it is always best to consult with your healthcare provider for further evaluation and guidance.
