Thanks very much. I was only intimate with the person who I contracted it from between my exposure and treatment. That's quite a weight off my shoulders.
The CDC advice is pretty arbitrary, intended to provide a big margin of error. In fact, people with gonorrhea generally are non-infectious within 1-2 days of starting treatment. Don't worry about it. (Of course your partner also should have been treated, if the two of you had had sex after whatever exposure was the source of your infection.)
