Cant find answers on google.. Help?

Ok. So I am about to be 30 weeks pregnant in a few day, and Ive had a pretty easy pregnancy, but Im starting to get concerned about this one thing. My breasts are not getting hard or sore at allll yet. This is a concern for me because I want to be able to breastfeed, and when your breasts become hard and such, isnt that when milk ducts are forming? I mean they have a liquid that comes out occasionally, but hardly. I mean is it still too soon? Should I be worried on if Ill be able to breastfeed? Someone help because google was completely useless
