What are the chances of pregnancy with BDing day 8 and ovulation around day 13/14?

I had fertile mucus - not super egg white fertile but watery on day 8 and CM continued to get more fertile until being dry on day 16.

I usually feel ovulation pain but didn't this cycle. I have had different symptoms that I can realte to my 2 previous pregnancies but am not sure if its my head.

By the way we are not TTC.
