I think the covid test lied. I feel better than I did yesterday.

So Saturday I started to get sick, chills, sneezing and a soar throat, then yesterday I felt worse. I had a fever, chills, headache, cough, congested, aching, running nose. I felt crappy. I got tested positive. I’m feeling a little better than yesterday but still not well enough to go to work. My temperature went down, my soar throat is gone, no chills. I still have a headache, congested, cough (but not as bad as yesterday).
Maybe I should get tested again because I don’t believe I have covid. I’m tested positive but I don’t wanna get fired.
