Test tweakers, help?

[Skywalker]

Any digital image editors want to help tweak these pics to see if there's a line or if I'm just crazy? Lol! I can't shake the feeling I am pregnant! Might be too early for internet cheapies to detect. Any help greatly appreciated! First pic today, two others taken a few days apart earlier.

I've inverted it and turned the contrast up for you on the second one... how many dpo are you? I do see a little something!
