Evap or Indent lines??

Wondering what anyone thinks about these? I had thought they were positive but I’m not too sure now. I was waiting a few days to test again just to be sure, and then I started bleeding today! It’s pretty bright and red and it seems like my period with pretty severe cramps so I’m lost as to if I just assumed I was pregnant. The first pictures were a little after the window so I retested with the last picture on the counter and that cake back within the time frame.
