Can my teeth move in 2 weeks?

I started Invisalign treatment 2 weeks ago. Is it possible for my jaw line to become narrow in this short time? My ortho staff did ITERO pics, and told me to go back in 4 weeks for the trays. Have not seen my Ortho since the initial consult visit. I have a small narrow mouth (deep palate) and crowed teeth. Will my smile become narrow to make space for my teeth? My ortho is a away for the next two weeks and I am so worried that my jaw line is becoming narrow to accommodate my teeth.
