How's the post flop play?

First of all, this is the first hand i've posted here, but i think i have all the info.

For a little background, this is literally the second hand i've been dealt into at the table. The table does, however have a very high average pot, and i usually assume that this has something to do with an aggressive big stack. Anyways, on to the hand.

I don't like the turn at all. I'm check/calling a small bet when the 3 hits the board on the turn. Clearly I think you're behind a straight from BB or the button (not likely though he is probably on a flush draw).
It seems to me like you've hit the BB special. Sucks to lay down 2 pairs though..
I must admit I'm scared already when BB calls your raise on the flop.
