I would guesstimate you are at around 15-16%. At 6 feet tall and 168 pounds, you need to put on more mass. If you cut now, you will look very skinny. The good news is your body fat is at a point that adding additional mass shouldn't create too much additional body fat assuming you eat wholesome foods and track your macros. For your height, you should be able to bulk up to around 180 to 185 pounds and still be relatively lean (in the 15% body fat range).
