Control line is really faint? 🤷🏻‍♀️

First test was 8/16/18

Second was this morning 8/27/18

I was supposed to get my period 8/21/18

Glow says I'm 5 weeks.

Last week I started having bad cramping and brown spotting. The doctor brought me in to get blood drawn for my HCG levels and I go again today. So of course I take the last pregnancy test in my house to see if it's gotten any darker, I don't know maybe to try to put my mind at ease a little until I go...

Well my test this morning my "pregnancy line" is darker than the "control line" does that mean anything? I'm getting mixed things off of google and I just wanted to know if anyone else got something like this.
