It was a nose one and I did it on my tonsils as well as my nose. Yes I'm an idiot. Anyway it came up as a very strong positive, a very dark line. I then did another one but just in my nose and got a very faint positive, probably wouldn't have noticed it if I wasn't looking! A proper squinted. Then I did yet another one and got a negative result.
I have booked a PCR but am I mad to think maybe it was a false positive?
