Nut flush draw and top 2 pair. Obviously a good flop for my hand. Should I've raised or is the call good?

TURN [board cards 4[img]/images/graemlins/spade.gif[/img],7[img]/images/graemlins/diamond.gif[/img],Q[img]/images/graemlins/diamond.gif[/img],2[img]/images/graemlins/heart.gif[/img] ]
cgdorty bets $1, westside_eh calls $1, toonman calls $1.

I thought that they probably both hit their lows here. Still had lots of cards to make me a winner and perhaps the 2 pair was good so called again.

cgdorty bets $1, westside_eh calls $1, toonman calls $1.

Should I have let this hand go when none of my draws hit? Called because I thought they both might have low hands.

What would you have done differently? How many times does the 2 pair have to be good to make that call on the river profitable? Thanks
