do not bulk yet bro. 17.2% is still high. I wouldnt start bulking untill you get to low teens if not close to 10%.
A general rule for bulking is if you can see your abs you can bulk, if you cant cut first then bulk. however, since you generally cant see your abs to approx 10% you are way off. but since you are so far off you might not want to go to 10% because you will lose some muscle mass. that is why i suggest low teens for you.
