Can someone help me out??🤞🏼

Hey guys so I got a FRER box of 3. On 2/24 it was stark negative.

On 2/25 I had brown spotting. And saw a vvvfl i thought.

2/26 I just took this one and it looks darker but I’m not sure.

These were from the same box including the first one that was negative. Is there a chance these are indents?? Or is it progressing?
