my dear mom as out there - HELP

Julia
I am 13 weeks and 4 days. And I got a very bad sinuses and not so high (100) fever. I feel like a track ran over me though... doctor told me to take Tylenol but it seems not to help. I am strangling thru the weakness and really hope my munchkin is ok. I don't even know how I caught it. I barely leave the house. And if I do, I put a lot of layers on... Did anybody went through the same thing? Should I be worried? Please help me with advise!
