Are indents common on these or am I pregnant?

I know a faint line is more than likely a positive but I never have used clear blue before let alone a blue dye test without knowing for sure I was pregnant. I just took this with FMU. All the pictures were taken at 4 minutes so it was within the window. I’m just not sure if indents are common on these or not? Thoughts? Just don’t want to get too excited if it’s a possible indent. 😅😅
