I have no symptoms. I have tested negative every two days for the past week and a half yet suddenly have a positive. So okay, incubation period maybe? But that means for the last week and a half I've had it and the tests haven't picked it up? I did a test Saturday afternoon and was negative, and didn't go anywhere yesterday after a ride with my dad (out from 8:30-3ish, but didn't go inside, didn't have any contact with anyone, was just me and my dad). So I doubt it's that I've just caught it so I don't think I can right now be at my most contagious.
I'll see and be sensible, but if I hadn't have had to do it for work, then I'd have been going about my businesses as normal and going to the gym, food shop, etc, would literally have had no idea.
Now I'll be doing none of that, but it shows that it really was complete chance. I don't even have a cold or a sore throat (or more than the usual grogginess from the antihistamines I take) which given it's the middle of hayfever season is mad!
I'm going to test again on Wednesday, so maybe I'll leave it until then. So yes, will skip the ride and be extra careful for people - though obviously worried about my parents now.
