Conception 🤔

What's the chances of me conceiving this cycle if I only bd on ovulation day and the day after? I got a positive opk on Wednesday night and due to me getting called in to work   Overtime all week I wasn't able to bd until late Thursday night but yet still I had a positive opk on Thursday night too... I honestly think my chances are pretty slim being as tho I really haven't bd all week except for yesterday and today.
