second nut flush draw

[Soh]

Hello,

good 10-20 game

Bad player (BP1) raise in early position. Another bad player (BP2) call 2 bets cold. Cut off (OK player) who just posted call. SB fold. I call with QhQd in the BB. 4 handed.

Flop came Ah4h2h. I check. All check to the last player who bet. I check-raised. Both bad players called 2 bets cold. OK player re-raised. We all call.

Turn came Ah4h2h-3h.

What's my play?
