The last 2 right?!

So I've been taking opk tests since CD15. I THOUGHT on CD16 I ovulated bc I had a dip & the test looked positive. Between then & now, I've had some close, some light. But today CD21 I had 2 DARK pos. Do I restart my dpo? Or continue with being 5dpo? Like I said no temp dip or anything. It's the same as yesterday. Picture of opk tests & chart! (My bbt chart is updated if I were to go by today's test btw)

•••••Edit to add•••• all my tests came back normal. I have irregular periods so the Dr prescribed me Provera 5/22-31 and I got a period 6/3-8th .
