Breast so sore. Help mommas!

I am 12 days postpartum and have been EBF besides beginning to pump a few days ago just for relief. My left breast is EXTREMELY sore. It has a red spot and the whole breast is warm to the touch. I am scared I have a clogged duct or might be developing mastitis. There are no lumps and I have been massaging, pumping, and nursing to get to help. I don’t have any other mastitis symptoms. Even after I finish feeding my boobs feel softer but are just as sore.

Is this normal? Help! Any tips?? FTM here.
