If you wanted to try something last minute you could do a jump and dump after intercourse (just get up right away, or after 5 minutes, and go to the bathroom, wiping away any extra semen) but this really does cut odds of conception and I'd for sure not do that with 3-4 day cutoff. You could also have DH take a hot bath before BD, again, this cuts odds of conception considerably and while J and D has seemed to add a little something in our results, hot bath is not proven and I'd be very selective in the number of things you try, esp. with a longer cutoff.
One final possibility is to add a "hurry up FR" to your attempt. On the day of attempt, have DH release once, dump that, then BD again as quickly as you're able to using only the second batch for conception. This should ideally be within 1 hour, 3 is ok, and up to 6 if it takes that long but it may not be effective any more by that point (so don't TRY for 6!) Even if you get past 6 hours before he's ready to go again, do still try, you're no worse off than you would have been otherwise!
