Vaccination Uploads Problem

i have a major issue. I had my first dose of Pfizer two days ago and won't get my second dose until October 6th. I realized i would miss probably one class but i had no idea you have to wait until 2 weeks after second dose to be considered "vaccinated". i can't miss that much. Will i be able to undergo weekly testing to remain on campus until i become fully vaccinated? kinda freaking out rn.
