Swore Breast 4 DPO

Jessica • 35 and trying for 2nd little one ☺️💕
I am very regular with my menstrual symptoms however this is throwing me off...my breast always get swore a few days before my period but it's 4 DPO and they are so swore I can't even lay on my stomach.  They've never been that swore before.  Is there anyone out there that's had a change in pattern of breast sworeness and not been pregnant?
