I’ve been unwell just over 2 weeks- horrific cold, headache tired etc, had 3 days off last week sick then felt slightly better went back to work Thursday and Friday (in a nursery where covid is rife). Monday DH tested positive but my tests on Monday and Tuesday were both negative, Wednesday and Yesterday both positive, faint lines but definitely there. Today my LFT is negative? Is it more likely I was positive before Wednesday and the test didn’t pick it up or that the negative today is right?
