I know your breasts will still grow during this pg but have you been properly fitted for a bra lately? It can make all the difference. I go to Myers and get fitted by the ladies there as I am a bit big (this mat bra is a 12F ) and they are just great (the ladies that is)!

My breasts are tender now, not sore as such, but bigger and hotter than usual, like they are already generating milk.

Hope it gets better for you soon.
