Evap line, how to tell?

[BBIvy]

How do you tell an evap line over a faint positive, or do they look exactly the same and there is no way to actually distinguish the two?
I did 2 and they both had what I believe is evap line, checked after the allotted time as got distracted by my toddler!

I know I just need to wait until AF arrives / fingers crossed it doesn't...but you know how it is!!

Evaporation lines are usually much lighter than your pic and are more of a shadow where you can't see colour....that looks like a BFP to me. Id be running out to get a nice brand test!!

That looks positive!

That doesn't look like an evap line to me

Thanks ladies, I did another this morning and it's darker so looks like it is! Praying it sticks xx
