There is no federal requirement for quarantine after arriving in the US. Quarantine requirements are at the state level.
According to mass.gov:
Quarantine is also recommended for unvaccinated individuals who have traveled outside of Massachusetts.
(...)
individuals who have received either two doses of the Moderna or Pfizer COVID-19 vaccines or a single dose of the Janssen COVID-19 vaccine, at least 14 days ago are not required to quarantine following an exposure.
So my understanding is that, in Massachusetts:
So there's no problem for you to leave before the 14 days.
Remember however that before travel to the US, you need to get a negative test less than 3 days before departure. CDC also recommends that you get tested 3 to 5 days after your arrival in the US in all cases, and self-quarantine for 7 days if you are unvaccinated (or 10 days if you don't get tested).
If you are unvaccinated, they also recommend avoiding being around people who are at increased risk for severe illness for 14 days, whether you get tested or not.
So, get vaccinated if you aren't already (if you start now you should be over the 14 days after the second injection by November), get tested less than 3 days before travel, and enjoy your trip.
