Burned a COVID test kit today [negative]

It's now 5 days past my most likely Minicon COVID exposure (the final party at our house) and I'm not feeling great. No specific symptoms except exactly what you would expect when the spring tree pollen count is peaking (which it is). But I am still so tired no matter how much I sleep. And there's a game party at our house tonight, so why not be careful? 

Test was negative. I'm fine, just tired out. 

I haven't heard of any Minicon-related COVID infections. Has anybody else?  Anybody else testing?
