Thoughts on my play BvB?

200 bb deep at $0.50/$1.00 ZONE Anonymous on Bovada.

Hero dealt 5d 2d in the SB.

Folded around and Hero 4x. BB 3bets to 12 and hero calls.

Flop Qc 9d 6d

Hero x/c 15

Turn (54) 4c

Hero x/c 33

River (120) 5h

Hero x/f

In hindsight, I feel like I should be check-raising this Flop as I only have 5-high. Any input or guidance would be really appreciated.
