Like always it depends on your opponent. You should call if you think BB is the type to bluff a turn after it's been checked through with overs or a Straight draw / Flush draw etc..I think the difference in EV between calling and folding here is very small. If you're unsure just remember your essentially playing a weak draw here and fold.
