Chance of pregnancy?

I spontaneously took an OPK test on Thursday (MAR 5th), it came back Postive. My partner and I where active late night Wednesday (MAR 4) and early morning Friday (MAR 6). We are both very new to this timing window for conception. I'm worried that we missed MAR5th that our chances are out the window.
