Please tell me that looks like an indent. It was taken at 4 minutes on a 3 minute test

I don’t see anything in the first the second I see a gray line so looks like an indent to me

I don't see any lines.

It looks like a gray line I had three of them recently. Wait two days and test again with a different brand

Get the.88 cent ones at Walmart I do see a line idk if it’s an indent line though
