I had COVID a month ago. LFs (Flowflex) were positive for about two weeks and then negative after that (I have to test regularly for work). Just done one now and it’s positive 🤷♀️ I had my booster on Friday but I don’t think that makes a difference? No symptoms apart from slight lingering cough from when I had it. Not sure what to do now. PCR would likely be positive anyway as infection quite recent.
