yes you should have gotten out of your stand to check for blood. just because a deer runs off doesnt mean it wasnt hit. my brother double lunged a doe at 12yards that ran 300 yards after ward. he shot her with a 300gr hollowpoint over 100gr of BP, which packs a wallop at a range like that and she ran off.
always look first. there will be other deer.
