If anything, I would have checked and see if you could have gotten the free card on the river to make the high. With 3 way action, it is very likely that someone has an A3 hand and wouldn't fold to a pot size bet on the turn.

Personally, I check and if someone bets the pot let it go. Two pair may get you the high if you don't hit the flush. But you are certainly getting freerolled for the scoop.
