I found one of my old lateral flow-test (4-5 days old) in my room while I was cleaning it, it was positive, took another test and came back negative. I thought I just had a cold, I still showed my parents the old test though and they booked me a PCR test. it took me a few days to even notice the lateral test was even positive. anyways, I went to the PCR test the next day and today I found out that its positive, and all of a sudden I develop a whole lot of corona symptoms, and on top of that I cant go to school till next Friday (which sucks because I love school)
