I say re test mine were like that with my last two.
I'd say positive, evap lines usually don't have proper colour or shape like that xx

Clearblue are really bad for indent and evap lines. I’d recommend getting a pink dye test x
Postirice
How old is the test? If it didn’t show within the first 10-15 minutes then I would re test
It looks like a faint positive. But take another one tomorrow in the morning to be sure
