possible pregnancy

Sara
I am about 7 days away from having my next period. 
I have and some nausea, aversions to sweet foods which is not normal for me, not heavy but thick white discharge, and an odd cramp in my lower left side of my abdomen, it's not crampy it's like I could pin point it with a needle. It lasted about two hours yesterday and the day before I felt it for a few minutes. My abdomen has also been a little fluttery.  I also had swollen and fingers and toes randomly a couple of nights.
Could I possibly be pregnant?
