Before anyone says, now bookings have reopened I have booked a PCR for tomorrow. Did a LFT this morning, negative. Started feeling worse so did another one a few hours later (my friend had this recently and was negative in the morning and positive by the afternoon, so thought I'd see). I don't want to do any more as we don't have many tests left. This one was the usual 4 drops and read within 30 mins. I've never had one come out looking like this. Is the line due to flooding do you think? Anyone else had this? Thank you!
