Sore breasts pre period or?

I've been having sore breasts for the last week can be super painful wearing a bra and the taking the bra off makes them ache too. The pain generates from the nipples to all around and sleeping in agony. I'm also getting pinching type cramps. I'm due on in 5 days do you think it could be just pre period stuff ? Never had breasts this sore before so a bit worried.
