Just check the river.

Also, this is a $4 pot to begin with, and you've now put $14 into it with bottom pair. If this was raised before the flop and there was some money to be won, go ahead and take a stab with your semi-bluff. With so little on the line, just see if you make your hand before you start creating a pot. 4bb pots are lame. We want the big ones.
