can I conceive by having sex a day before a positive opk?

I had a positive opk on Friday 5th. I bd'd on Thursday 4th and Saturday 6th. What are my chances of conceiving? I know it's only about a 25% chance every month but are my chances high or low? My friend said my chances are low because I didn't bd on the day of the positive opk.. Just wanted other opinions x
