Congrats on your pregnancy I had the same thing as you, breasts weren't sore at all! I was worried too, even mentioned it to my ob when I saw him at our visit and he said it is nothing to worry about. I guess the breasts have already created what they needed to last time. Mine just gradually grew over a few months. Very occasionally they would hurt but not very much, but that was when I was further along. It's nothing like last time!
