Was notified as being a close contact just over a week ago and advised to do 7 day testing. I have bulk packs of LFTs from work and was actually testing twice a day due to vulnerabilities in my family. I picked up a really feint positive last Sunday and went straight for a PCR which came back positive. Out of curiosity I carried on with daily testing and hit peak positive on Tuesday. Wednesday was weaker and Thursday and Friday were negative. I was therefore happy that I could be released on day 7. However, I’ve gone the day 6 test today and it’s come back positive. Has anyone had this before?
