Signs?

Had a weird pain I’ve never had before last night. My breasts are swollen and hurrrt. They’re also really veiny. I’m 2-3 days til AF. Last night this pain came up around the top of my breast/chest area, and into my lower armpit area. It was a sharp pains that just wouldn’t go away. Has anyone had this before? pregnancy maybe? I had cramping 8/9DPO. Trying to wait until expected AF to test
