Agreed with ewurm, stop wc-ing and let it cycle. You need that ammonia to feed your BB and get your cycle going. If it gets really bad you could do one (like >20ppm) but otherwise let it happen. How big's the tank?
I would feed them the morning of the day before you leave, then do a gravel vac and small wc (just enough to vac) that night to get any crap out; you want minimal old food and fish turds when you're gone. When you get in halfway through give them a small feeding, and when you get back test and do a wc if you're over 20ppm again. That's what I'd do anyway.
