Weird symptoms..

Ca
I first noticed my nipples ( not boobs ) wore sore. Not extremely, only when I pressed on them or when I took my bra off and it rubbed them. well they still are tender a week later but not as bad. They just feel bigger? fuller maybe ?
And everytime I get something to eat I just don't want it anymore and throw it away.. 
I'm always nauseous and fatigue so that's nothing new lol
