Help ovulation and clomid.

So I’ve been using the clear blue advanced ovulation tests since cycle day 10 today is cycle day 13. I took clomid cycle day 5-9. I’ve gotten low fertility symbols the last 2 days then this morning I got a peak fertility symbol. So I just skipped right over high fertility? Is this normal, has it happened to you, and if so did it result in pregnancy? And I called my dr. And they said still have sex cycle day 10-20? Why keep having sex if I ovulated today, on cycle day 13, do I still have a Chance of getting pregnant? Also I got for a 21 day progesterone blood test on the 11th.
