Ovulation tests... help...

Co

The top 2 I took yesterday the bottom 2 I took this morning.. are any of them positive ? One pic with flash and one without..

I'm also on CD 52 and my period hasn't shown any signs. I thought I started like 3 days ago bc there was blood when I wiped before I went to bed, so I wore a pad thinking it was my period and there was brown blood the next morning on my pad but there was non when I wiped and no more spotting after that.
