Too soon?

Jennifer
Hello ladies! I'm due to start my period in two weeks (12/18), and am supposed to take a pregnancy test next week (12/11). I feel that I've been having some potential pregnancy symptoms, things like:
•nausea, usually throughout the day, but particularly strong in the morning and at night
•more tired than usual 
•abdominal cramping, similar to period cramps but not quite as intense
•decreased appetite 
•cravings for particular things, and not 
wanting things I usually would like 
•moody/irritable, very emotional
Would it be too soon to take a pregnancy test? Would it be able to pick up the HCG this early (if I am pregnant)?
Thanks y'all!
