6 weeks flu like symptoms

Megan
I'm 6 weeks today and still haven't really had any throwing up or extreme nausea but, I've felt like I have flu symptoms the past two days. Tired, groggy, slight headache and slightly dizzy. Overall feeling crappy. Of course, this is probably normal but worries me. Anyone else feeling this? At this point my boobs are sometimes sore but not always and still having a little pinch or two in my uterus but, I'm kinda ready for some "tell tale" signs to soothe my worry. We are avoiding sonogram until 20 weeks and won't be able to do blood testing for 2 weeks probably so it's just scary wondering "are you still in there baby?"
