In case others read this, as I do notice this is an old post, having someone crack you back like that is not really smart because they could potentially hurt you or break your ribs if they are far heavier or clumsier than you anticipated. I wont say I haven't or don't do this technique but this should definitely shouldn't be attempted on a pregnant woman at anytime, if you want to crack your back on your own try stretching or sit in a chair and turn toward the back of the chair with you legs still in the forward position. Again not really safe if you cant gage your own strength but better than neone else doing so.
