Not getting darker?

I have been testing for my own peace of mind until I see my OB just to see I see progression. At some point it got to where the test line is a little darker than my control line. Tbh, I am expecting my test like would steal all the dye at some point but it never it. For some reason, I feel like it's not even getting darker anymore. I usually test as soon as I get home or when I wake up first thing. What do you think? Do you see progression? Am I just freaking out for nothing? This is my first little bean so I am really scared. I am 6wks 4 days today. The bottom strip is from few minutes ago. Thanks guys!
