What do we think?! Vvvfl?

I think this is a vvvfl ? Popped up after about 3 mins. I have had indents on these tests before so I’m very very cautious! But this looks a bit darker than my previous indents ?? What do you think- colour or no colour ? Is this the notorious FR indent or a line?

Maybe I’ll wait a few more days and test again! Thanks 😊
