Period due in 4 days, very very faint line on frer

Supposedly period is due in 4 days, was gonna wait till Friday to test but obvs I didn't. Like all or most frers it shows a indent line which goes after a few minutes, but I could still see a very very faint line, used my torch light on it and it was showing some pink colour so could be positive! Anyone had/done something similar?

(and yes, pic was taken within 3 minutes of being wee'd on)
