Please don't fret too much, Mamacita. Your primary therapy was surgery, and your chemo-radiation is the followup. There are variety of studies showing a variety of results: we don't have a really big study comparing the big bag vs weekly with HPV positive tumors. The doctors and statistician can beat the available data, but I'm afraid you will need a time machine to get a more definitive answer.

From what I have read, keeping the radiation on schedule (especially early on) should be your primary objective.
Best wishes,
