Flush draw - misrepresentation

[Roy6]

B2B €2/4

This is my first hand at the table, so no reads.

MP limps, CO raises, Button coldcalls, SB calls, and I call in the BB with J [img]/images/graemlins/heart.gif[/img] T [img]/images/graemlins/heart.gif[/img]

Flop is 4 [img]/images/graemlins/heart.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] Q [img]/images/graemlins/diamond.gif[/img]

checked to CO, he bets, Button, SB call, I raise, MP folds, CO, Button and SB call

Turn is Q [img]/images/graemlins/club.gif[/img]

Should I bet now? Do I have enough folding equity here?
