Worried

So I took a test two days ago and it was faint but very clearly positive, I took one yesterday and it was a little bit lighter in color, and I took one this morning (around 7am but I had gotten up to pee around 4am) and it almost wasn’t even there. So I took a pink dye test at 6 pm tonight and this is the result. AF was due today, I can see a little something but shouldn’t it be so much darker if AF is due???
