Call two then fold the flop?

SB seems solid (15/6/2.5)
BB is is little LAGGY pre, passive post (33/13/1.0)

Should I have called two more because of the back door flush draw. That's why I called the first two.

Should I have 3 bet the flop or just folded or was my cold call OK?

Feels like I'm behind at least one if not both of them and my outs are all very dirty outside of running hearts.

Only thing I liked about this hand was my pre-flop raise.
