What days to BD? Expect +OPK tomorrow

We have family in our house this fertile week (great timing), so we had to preplan when to BD this month. I expected a positive opk Friday or even Saturday, but now it looks like it’ll likely be + by tomorrow. We haven’t BDed yet, but will tonight.

Should we BD again tomorrow or would it be better to wait for Friday and let the sperm buildup? He unfortunately emptied the tank yesterday thinking we were waiting until tomorrow… just worried we’ve ruined our chances.
