Chemical pregnancy?

I need help!

I took these these over the past few days my test on 10-30 and 10-31 show a very faint line I even took a first response on 10-31-23 (not pictured) which also showed a faint line. Today I took another first response and my line is even lighter does that mean this could be a chemical. I use two different apps my glow app says I was suppose to start my cycle today and my other app I use says I was suppose to start my cycle on Monday 10-30-23. Still no period yet. Looking for advice. This has never happened to me before. Each time I’ve been pregnant my test have always been clearly positive.

Taken 11-1-23

Taken Monday 10-30-23 and 10-31-23
