Line after 30 mins - false positive?

[WhatNoReally]

I tested today as a friend I met Monday tested positive and after I developed headache /nausea. The test was negative after 10 mins then I forgot about it. Checked 2 hours later and there was a faint line. Anyone have any experience like this and did it turn out you had covid? Thanks

Could be a false positive but tbh I'd do another one and read it at the right time. The line can be very faint so use a light to view it.

This happened to my DS. Was neg at 30 mins but a faint positive by 45. It was very clearly positive the next morning. I suspect yours will probably be positive if you repeat it tomorrow.
