No missed period yet but i have some symptoms.

I haven't missed my period yet. But i've been feeling weird for the passed week. Nausea, hyper salivation, cramping. The symptoms don't come all at once. One fay i would experience one or two the other day one would be gone. But i'm always feeling weird. My nipples were very tender last week but not so much now. But the nausea as been really bad for the last 3 days.

AF should be here on Wednesday....

Also is it weird that everything smells awful to me ?
