ff got my o date wrong now have new o date but worried about timing

[corrie anne]

I'm on cd85(yes 85) i am breastfeeding. Ff had my 9 date on cd67 but when i thought i was 9dpo i had ewcm and ovulation pains. So we bd only on the day. Now that day IS the day i ovulated. And the only time we had sex. Are my chances skim because we didn't bd before ovulation? I'm 8dpo today and af was due today because of my short luteal phases.
