The only thing I can think of if to check your gravity right now, and see how it compares with your FG. That way you'll be able to tell if the sugar fermented out by bottling day. I'd think 4 days should be enough to ferment the sugar out.
~Edit...duh, just realised this was three days ago. Little late for a hydro reading now! Still, I'd take a hydro reading on bottling day. If it's the same, or lower than your measured FG, re-prime and bottle. Say a little prayer, and put the bottles in a secure area.
