It's me again lol

I keep posting about pregnancy tests and my positives that are faint, then I'll fail another one and so one... Well I tore apart the digital ones to find the same faint line that I keep having on the other ones. It seems to me like I get a darker line when I pee once or twice in the morning then hold it from 3-6 or 7 then take one. How is it that my afternoon pee is better than my morning???? Here's what I found from the digital, I did the bottom one yesterday evening at 6ish. Maybe later. After holding my pee from 3:30. I did the top one this morning from my first pee... 
Now.... The first one from here on will be an afternoon one. And the second will be from the morning.... 
I'm just wondering why it's so opposite of what you're told to do. It's always noticeable in the evening. But not in the morning..
