Is this a call on the flop?

[squiffy]

I was playing $1-$2 at a loose passive table. Usually 5-6 people seeing the flop out of 9 at the table.

I called $1 with Ah,2h from early MP. Thought about folding it because of the low kicker. But no one was raising so I called. There were about 6 people seeing the flop.

The flop was something like 7s 4h 2c

It is checked around and a late position player or possibly the button bets $1. Assume you know no one will raise. Is this a call or a fold? [You have bottom pair and high kicker. And three hearts.]

I called, but think now it may have been incorrect.

The turn card was something like Qh. Now I had a four flush.

There was about $10 to $12 in the pot. The button bet $2. I called. Two behind me called. [Was this call correct in terms of implied pot odds.] Clearly I would really want 4-5 bettors to make my bet worth it. But don't the implied pot odds make it reasonable now to call?
