Yup, this. Give it more time. Be patient.
also, be sure your glasses are beer ready. If you run them through a dishwasher, stop doing that. Wash them by hand. To return them to beer ready state, wash them with salt and a touch of water to scrub off the "streak free shine" stuff left behind by dishwasher detergents and Jet Dry.
EDIT: the glass cleaning won't cure the head retention problem at 2 weeks in the bottle. It's just a PSA so you don't end up carbing properly and looking for problems in your process when its just a glass issue.
