Is this positive?

I need help! I took a pregnancy test today, my af was due today (according to apps, not sure how accurate that is)

And the test originally looked completely negative. within 2-3 min I started to think my eyes were playing tricks on me.

I saw a line but it was so faint that I couldn’t even get a picture of it. So after 5 min of starring and wondering and driving myself crazy I took the test apart. That’s when I saw the very faint line.

It’s continuing to get darker now (of course)

But I need you guys to tell me if this could be because I’m actually pregnant or just an invalid test?

Should I test again in the am or wait until Sunday am?
