Over the course of five weeks (early Sep to mid Oct), I have had twelve faint positive lfts (can't find a button to attach a pic...?) which was about a third of tests I did during that period of time (on four or five different brands).
The three pcrs I took were negative (the first two seemed to be taken very quickly - briefly touching the back of my mouth for a split second, no twisting the swab or leaving it there).
Never had symtoms and I am unvaccinated.
Is it likely that I had very mild Covid? What other explanations could there be? Btw, I am the only person in the household to experience this with the tests, and I am not based in the South-West. For full disclosure, I have an antibody deficiency so a blood test wouldn't clarify the situation...
