Confused

I cannot function at this point.

I had taken a test around the 13th which was my AF date on this app and got what I believed was a faint positive. I’ll add the pictures of that.

On my other app my expected period wasn’t until Christmas Day which is crazy seeing how my last period was Nov. 13. On the 23rd I started bleeding but it only lasted 4 days and was super light compared to my usual 6-7day heavy periods.

Has this ever happened to anyone?

This was taken on the 13th within 3-5 minutes

This was taken tonight and looks like it could be an indent.

Help!
