I am not a great tracker, but I have been with a few great trackers that showed me a lot. Try and pick up the deer's actual track and follow that track as much as possible. Once you establish the that deer's track, stay on it. It will become clear which direction the deer is going.
Go slow, scour the foilage at the height of the hit. Look at brush front and back for blood and also for broken branches, trampled grass, sticks, and hoof depressions beyond casual walking.
Pretty much anything that would indicate a quick retreat is probably your animal.
I am usually so amped after the shot, I have a hard time focusing. If you have anyone that can go with you, take them and I mean anyone. They won't have that anxiety to find the animal all built up like you might have.
I have a hard time tracking my own animals, but a much easier time tracking a friend's animals. I don't know what it is, but that is what I have found.
Stay with it and you should find her.
Good luck,
Paul
