Took a LF this morning and the faintest shadow of a second line came up so have already been and had a PCR test. I'd probably not have spotted it as positive had I not read a few threads on here saying about really feint lines turning out to be positive after PCR tests. Anyway, just did another LF and it's a clear negative, anyone else had this and if so did your PCR come back positive or not? I know I've got to be patient and just wait for the results, but I'm already bored hence posting!
