Very hard to explain, and will probably sound really weird, but hey ho...
I seem to be producing some kind of milk or something already, at 11 weeks. My nipples have kind of white spots in them (the actual nipple bit, not the surrounding monstrosity). 
I can pull the bits out if I so desire (sorry, that is far TMI), but they are replaced again by the next time I'm ogling them suspiciously in the shower. It is kind of in the holes where my milk came out when feeding DD. And I don't remember this when pg with her. To be honest, it's freaking me out a bit!
Someone tell me this is normal. DH says it must just be because I fed DD for a year or so and my ducts are just loose or something!
