A little help

Can anyone tell the difference between PMS sore boobs and pregnancy sore boobs? Been having sore boobs that seems to be getting worse and worse by the day. Started having on amd off nausea but it seems i cant shake it off tonight, no matter what i do. Tested negative yesterday. Today would be 11dpo. I've got mild cramps not crazy pain like the ones before my menses, started 4 days ago, just on and off tolerable cramps with constant headaches. I intend to test tomorrow tho, but just want to lnow as i dont want to raise.my hopes up.
