Early pregnancy signs or imagination?

Maddie
Af is due Tuesday but scared all might be in my head and not real.
I am feeling/experiencing the following:
extremely bloated with cramping(look pregnant),
nausea & sensitive to smells,
stuffy nose,
headaces,
​creamy CV,
​nipple discharge(very little) 
​Anyone experiencing the same?
​Or someone with BFP had the same symtoms?
