Negative test but some pregnancy symptoms?

Amber
Negative test but some symptoms. I know they could also be AF symptoms but I've never had sore boobs before. AF is due tomorrow so I know I tested early but I've had incredibly sore boobs/nipples, my areolas have become puffy also, happened to anyone else? My armpits are tender and feel as though they have a small lump in either side? I'm unsure of what this is. If it doesn't go I will go to my GP. I've been tired and my appetite has gone from 0-100. I don't want to test again until AF is late by a week. 
Anyone had similar or different symptoms?
