I see something

I have never seen this before. My cycles are pretty irregular but I felt like I ovulated 9 days ago. So today I thought "what the heck, why not test just for fun?". I have never seen this appear on any past tests (I have probably taken over 100 in my life). Is this what you call and "indent line"? Or what? I will retest in a week. ETA: sorry the picture is upside down.
