Samantha I can see that in the first image anyway! Mine was SO faint on Monday, then I did a digital test and got Pregnant 1-2 weeks, so would you try a digital test, just in case? They're expensive little things though! But I figured at least I wouldn't be squinting, moving the stick, seeing is it/isn't it etc.
OK sam not so easy to tell on the original I agree something does catch your eye though but if it is a line it is super super super faint how many dpo o are you ??
