I started Invisalign this month but haven’t been very good with trays due to work. Invisalign potentially making my teeth loose?

I’ve been sick the last week and a half. I wore my trays for a week (first set) and then stopped when I got sick. I was able to restart and then I went about four days again not wearing them and now my front are loose! I feel like they shouldn’t be loose on my first tray and the fact that I haven’t even worn them long enough for my teeth to move scares me! Should I stop treatment or keep going to stabilize?
