Shane,

I had a very similar situation to you about a week ago. I hit the deer at dark and knew it was a gutshot, with the arrow in it. No blood to be found. Waited for six hours. After crossing a field and guessing where it went in the woods, we found a few small drops 10 yards apart to guide us, as well as a gutty arrow. Ended up jumping it even after waiting six hours. Watched where it went with the spotlight and backed out again. In the morning, to my surprise, it was not there. I ultimately found it that evening. I was amazed, but it had managed to move another hundred yards away, and in thick stuff, that can be a big obstacle. Try expanding your search a bit if possible. Also, look for the small blood drops like was said. Even just two pin-head sized drops five yards between them can give you all the help in the world by showing a direction.

Best of luck. When you said WC did you mean west central pennsylvania or west chester, PA?
