[25NL] AK - hit flop, check raised on turn

[selector2006]

I just started at this table so I don't have any info on opponents.

I'm UTG and get AK. I make a standard raise to $1. Almost everyone folds, only the SB calls.

At the flop I hit my A, but there's also a Q. That's a little scary. There's also a flush draw. I make a c-bet on the flop. The SB calls.

The turn is a pretty harmless card I think. I make another bet because I don't want the SB to draw cheaply to a flush. But then he raises me.
I don't want to risk my stack with only one pair, so I fold.

Easy fold? Or reraise all-in? Or just call?
Should I have not bet the turn?
