I think all hunters go through a stage where they have plenty of sign, but no activity. Actually, it's probably going to happen to you more than once. Two years ago I went out 14 times before seeing anything. Moved the stand twice, and then one morning I saw three does and continued seeing deer on a consistent basis for the rest of the season. Things will definitely pick up during the rut. Trust your stand location, as well as your scouting abilities.
