I can assure you with one thing. If you were in a dire condition, they wouldn't be making you wait. :) They'd have sent you to the hospital and had the results that day.
It can be stressfull, but as long as you're not too weak to stand, seeing stars, or overly dizzy, I'd say you're okay to wait. :) However if you are experiencing those symptoms, I would get checked out of course at the hospital. But honestly if you can function right now, you're fine right now... and that's sorta where we have to keep ourselves, in the here and now.
