Boobs! Leaking...?

Rose
So I'm 26 + 4 days and my boobs are huge... I have gone from a B to a DD.. I'm not surprised really but they are covered in bright blue veins and leaking milky gold mixed liquid... why so soon? This is my 3rd baby I have 2 big kids who are 6 and 8 but I never had this until at the earliest 38 weeks... I'm just wondering if anyone else is or has this early on?
