Congratulations on your doe kill!!!
Several years ago, I shot a buck that was quartering away and the arrow hit behind the right front leg and like your shot, this one didn't exit either.
The buck fell on his face (broke the off-side shoulder), got back up and ran 25ish yards and fell over dead. There was about 3" of aluminum shaft missing, on the XX75 Camo Hunter 2216. After carefully field dressing him, there was an "X" on the opposite/exit side of the ribs, but the broadhead never left the deer. The meat processor carefully followed the wound channel down the leg to find the Hoyt Bow Bullet 145 gr. 4-blade broadhead, laying along the leg bone. Pretty much like your broadhead was found on the doe's leg, that's where I found this broadhead, on the buck's leg.
