when did your breast change?

I'll be 9 weeks tomorrow and I hear the most number one common symptom is sore boobs. Mine feel fine. Some days they feel a little tender but only if I press on them. The only thing I've noticed is sometimes they look really vainy and they itch a lot. Other than that they don't hurt or don't even look like they're growing(which I'm probably still to early) so just wondering if it's like normal or it just happens later on?
