I had leaked from 24wk with my first pregnancy and this one I leaked before I even got a positive pregnancy test but just knew that this was a sign that I was.

I have had engorged bb's and what we think was mastitis at 15wks preg too. Bloody hormones is all I can say. I don't mind though at least like you say it could be a good sign our milk supply is going to be a plentiful one.
