Any ideas?

So last night I took a 99 cent store test and came up with this. I took 5 in total (I know I over did it 😆) but 3 were insanely faint and 2 were like this picture. This one is the darkest one I’ve had so far. I’m 5 days late from my period and today I took 2 more test and now its like the original 3.. VERY FAINT, took a digital it said negative.

What do you guys think? Could I be pregnant rn and it’s just way to early and that’s why the test are so random in darkness or could I not be pregnant? I’m so confused. I have a doctors appointment Friday but this is all I could think about rn. I really feel like I’m pregnant.. but the test just aren’t consistent at the moment.... thoughts???? 🥺
