Sick and miserable.

I am 16 weeks today and MISERABLE. My temp has been up and down. I’ve been doing Tylenol and lots of fluids. Tested negative for strep and the flu. I went to my OB today just to get checked out and all is good with my baby. My nose is SO stuffed and literally pouring snot. I have tried just saline spray and Flonase. I’ve taken two steamy showers. Nothing is working. I want to bash my head into the wall right now I feel like so badly. Does anyone have ANY other suggestions? I will try anything. 😭
