Don't count on exactly two weeks for carbonation. Could be shorter but more likely two weeks or longer. One trick you can try is to get one PET (plastic) bottle, an actual PET bottle made for beer would be nice but a soda bottle will work. You will be able to feel the bottle firm up as the beer carbonates.
It helps if your bottles are in a warm place. 60s to ferment is nice but 70s will help carbonation along.
