following effected treatment from your gyno with the standard azithromycin or doxycycline is normally not recommended. Exceptions include women who have persisting symptoms or if you are actually pregnant. But be sure to stretch that test out at least more than three weeks or you might test positive for organisms that are there, but not really viable (dead). Guidelines issued by the CDC distinguish tests of cure from repeat screening, which should be considered within the first three to four months after therapy is complete. And also think about what other STDs you should be getting a test for. Once you test positive for one, you might have another.
