Sick or feeling prego symptoms?

Nikki
I really can't tell if I'm getting the flu or if I'm just REALLY feeling the pregnancy symptoms  lately...
-Waking up super naeseous, (no vomiting, but gaggy) 
-feel really tired, sort of weak 
- stuffy nose , which makes me think maybe just a cold? 
- loss of appetite , NOthing ever sounds good :/ 
Anyone have any ideas or suggestions? I didn't feel this bad a week ago!
