I have questions!!

So the top picture I took one day before the other pictures. How is it possible that the line just brightens up over night! I was only one day late when I tested and the clear blue I took when I was only 2 days late. Is that normal? When I found out I was pregnant with my son I was 2 periods late. (Didn’t track it and sometimes I would miss a month) so the lines with my son were extremely dark but this time around I’m curious
