Could I be pregnant?

For a week I've been having symptoms as such:
Nausea/vomiting (mainly after I eat) 
Extreme tiredness (almost like I haven't slept for days) 
Sore breasts/sometimes nipples (every once in awhile it's not a constant pain)
"Fullness"/cramping in my lower abdomen.
Frequent bathroom breaks. 
And VERY moody lol. 
AF isn't due for 12 more days. HELP!! Don't know if I should test now or not. (Tested other day with clear blue digital and got a BFN😔)
