Y’all is this the notorious indent talked about or a vvfl?

I’m to my best knowledge 6 dpo per opk but just had a weird cycle so totally possible I could have ovulated early but who really knows because I don’t temp. I never test this early but I just had to do it to get that first bfn out of the way to convince myself to wait. BUT I tested and this thing popped up within 2 minutes of the test. I’ve heard of the indents on frer but have never had one, so is this what they look like?? Thanks for any help so I can know in the future and maybe help someone else out too!
