I've just finished isolation earlier this week as had asymptomatic covid and had a positive result after being asked for everyone to do one as a precaution for work.
I isolated for 12 days and went back to work as normal as I felt great and my LF's had been negative for a few days prior.
I've now done another lateral flow last night as I had a headache and heard this was sometimes a symptom - LF was positive.
I've woken today no headache and feeling good and done another lateral flow and it's negative.
Wondering if it's worth doing another PCR as I've heard it can still show positive If I've recently had covid - which I had.
Advice please?
