Maybe baby.

The past week I've been getting headaches all the time, feeling really hot in bed even though hubbys cold, I've had 2 days where certain smells were making me slightly nauseous, and been very lethargic.
AF is due in three days and haven't been feeling any small twinges of cramping yet and also have discharge that I don't usually get so close to AF.
Tested a few days ago but it was negative, but was probably to early to tell anything anyway. 
With my symptoms could I be pregnant?
