Progesterone question??

So I’m not sure if anyone will have the answer, but when is the latest I could’ve ovulated? 8/4 mg level was 13.5 confirming ovulation, but as of 7/29 I still hadn’t had a + opk.

Could I have ovulated 8/1-8/3 and it already be that high by the 4th?? (4th was CD22)

My period was due yesterday and still nothing, but neg tests still. Please help, I know nothing about progesterone!
