What are the good days when ttc?

I am on day14 of my cycle and we bd on day 10 and 11 because I got a + opk on the morning of day11 and ov pains that night, we bd right after that. What's weird to me is I have a 28 day cycle but ovulate early. Did we bd on the right days?? Should we bd today since AF will come in 2 weeks??
