I would have shot her last night also. I've had to finish one off after dark. The green crap on the arrow could also have been from the arrow passing through her food pipe. It's happened to me. Perfect shot from above through a lung the food pipe and out under the off side shoulder. The arrow was covered with green gook, but since I saw the hole appear in the deer when I shot(only about8 feet up in another guys stand) I was sure of the hit. Terrible blood trail but he only made it about 85 yards.
