Payment plan due tomorrow but financial aid still showing $0, will I be disenrolled?

My payment plan installment is due tomorrow, but I currently have $0 anticipated financial aid showing because of the financial aid delays. I literally cannot afford to pay the installment out of pocket. Does anyone know what happens if I can’t make the payment tomorrow? Will I be disenrolled from my classes, or is there some protection/extension for students still waiting on their financial aid?
