So I tested last Monday for work purposes on a LFT I got the faintest positive... that faint that no one else could see it haha! By Wednesday it had got darker but still faint! I did aPCR which was negative.. still tested positive up until today which has now barely visible again.. waiting on another PCR that I did yesterday.. what are peoples thoughts on this? I've probably done about 10 positive LFTs... not symptoms other than slight stomach cramps mid week.. slight nausea and slight fatigue? Strange how this has happened, I'm trying to think of anything else can cause these positives??? Help
