Question about small flush

don't have the HH, but it went down like this:

I had 3c,4c in small blind. Completed, and saw jack high flop w/2 clubs. I threw out a pot sized bet (.12, don't laugh). Had two callers. Turn was 8c, completing my draw. Pot was .48, I bet .50. MP called it down, the button folded. At this point I was worried about a larger flush, as mine was pretty wimpy, and MP play seemed to be consistent with a drawing hand. River card was a blank. Pot size is $1.48. What's your play in this situation? Again sorry no HH. :(

Was the jack on the flop a club? Could be he holds Jc, had top pair on the flop, picked up the J high flush draw on the turn, and wanted to stick around...Or it could be another jack with K/Q/A of clubs kicker that picked up the draw on the turn too...

As long as the river wasnt a 4th club, i'm pretty comfortable with my 4 high flush. I bet 75 cents on the river for value, and hope i don't get re-raised too big.
