Is this positive of negative?

Trying to work out if it's positive or negative, yes it's within the time scales but can't see any colour on it

Positive

Positive. Will likely come darker over the next few days if you're just starting to feel unwell

Positive

Thanks I have never had one like that, when I have had covid before they came instantly positive so wasn't sure as it took about 5 mins to come up.
