Okay now I’m confused!!!

So I posted yesterday saying I was 6dpo and I got confused because I got what looked to be my period

This was 6dpo.

This is right now at 7dpo it’s already ending, usually my period is the heaviest the second day but it seems to be ending already there’s barely even anything??

Everyone told me it was my period but now I’m not so sure anymore ?? What do you girls think
