Did I do anything wrong?

[Phineas]

I am pretty new to the game and want to know if I played the hand wrong. Should I have checked on the turn and seen the last card cheaper or did I do the right thing by betting? Is this just one of those things that happens and you just have to put up with it, or can you minimise these sorts of losses?
