I have shot and seen many deer get shot and NOT leave a blood trail, some never did, , some it took a while for it to start leaking up
so, yes 100% you should be out looking NOW<
try and follow the path it ran and to where you last seen it, and search from there out in grid search patterns
if you know anyone with a deer tracking dog, or know of folks in your area that ofer the services, call them FIRST and take them with you, a dog will find things WAY better than a human will!
and there worth the costs when ecovering a deer IMO, if needed!
