Invisalign Pain After 3 Days?

i have had invisalign for 3 days. They fit fine everywhere except the bottom back right side i can even push it up with my tongue The plastic also seems to stick out (into my mouth) from my teeth and gets caught on my tongue everytime i try to speak I know that they had trouble taking the molds of the backs of my teeth so i am starting to feel like they must have done something wrong. how do i tell if i just need to suck it up or go tell my ortho. I don't really want to talk to him though...
