playing a set of 3s

[Navers]

Home game, blinds are $.05/.10 so as you can guess given the blinds, the game is relatively loose. 8 players.

I'm in SB with 3 [img]/images/graemlins/diamond.gif[/img]3 [img]/images/graemlins/club.gif[/img]
4 limp in ahead of me and I complete.

Flop: 3 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/heart.gif[/img] (5 players| pot is 50)
I check intending to raise, it's checked around. [img]/images/graemlins/shocked.gif[/img]

Turn: 10 [img]/images/graemlins/club.gif[/img]
I bet 50c, MP calls.

River 8 [img]/images/graemlins/club.gif[/img]
I bet 80c, MP calls.

Should I have check-raised the flop here?
