Continuation Bets on Flop and Turn

[taks]

I do not have any reads on BB and CO. Even though there is an Ace on flop, I bet on flop since the board was relatively uncoordinated. Turn - 3rd heart comes, but I bet out anyway. I was planning to fold if I get raised. River - 4th heart comes. I checked and called here. Do you bet on this flop and turn? Comments on all streets are appreciated. Thank you.
