Flu+Pregnant=the worst

I'm sure there's already been a post about this but I couldn't find it. I haven't been to the doctor because I'm pretty sure there's nothing he can do. I have flu symptoms; sore throat, stuffy nose, running nose, a cough, headache and fever.
The pharmacist told me I can't take anything. LITERALLY nothing. Not even vitamin C because it's already in my prenatals.
Any suggestions? I am not one to usually complain about sickness but this feels like one of the worst times I'm ever been sick.
Should the fever worry me?
When is it time to seek medical attention?
My SO keeps making me tea as if that wil heal all lol....
