52s in the BB

[Brian462]

Party 25 NL 10 max

I don't have any individual reads, as a whole the tables seem to be a bit more aggressive than usual, but not by much.

I have 52s in the big blind and theres 2 limpers, and the SB completes. I check.

Flop is Jd 3d 7c - giving me a flush draw and I guess a backdoor straight draw.

The pot is about 2 so thats what I bet out. All 3 players call. With everyone calling I think the chance is very high that at least 1 of them is also on the flushdraw in which case mine is likely no good.

The turn is a Kc and the SB checks. I check, as do the 2 other players.

River is 7d giving me the flush but pairing the board. I am still worried that my flush isn't good, especially after all of them checked through the turn. SB checks, I check and MP checks. The last player bets 15 into about a 10 dollar pot. I fold.

Weak?
