Possible chemical

Updated: these was all positive I'm just early. I got two obvious positives today.

I'm so nervous. Iv had multiple faint faint lines like very faint but there on multiple different test a few first response and 3 different $1 test. I'm 2 days away from af I have some symptoms but I can't go off those as I've been extremely stressed from losing my grandma a little over a week ago. I would've convinced on the 10th so it should've shown a decent line by now. These are a few of my tests. Opinions please? Is it just to early or a possible chemical?

^ taken today almost couldn't see the line.

Same test that was above taken apart.
