I have tested every time I've come home from a work trip since the pandemic started. Always tested negative, including on Friday. I had a little bit of a cough when I got home plus a runny nose, and honestly wouldn't have thought to test again, assuming I had a cold, if we weren't going on vacation next week. So I decided to test again just to make sure I'm doing all the shit I can do to make sure I'm negative by next week.
I did feel a little extra tightness in my chest this morning which helped make the decision for me. As an asthmatic, it's alarming to be getting chest tightness when you don't have at least some idea where it's coming from, but I still most likely wouldn't have tested if we weren't trying to get out of town next week, though.
Also, feel more sure that I did get COVID in the first wave right when lockdowns were starting. Cough, runny nose, chest tightness for a couple days after a work trip to New Orleans. There weren't any tests then for me to find out for sure, but if this goes the way it did then, I should be back to 100% in the next couple days.
