How many refinements does Invisalign Lite include? 

I'm worried about a gap forming in-between my front teeth. I took a closer look at the Clincheck, and the gap will only get bigger. I can't understand how it got approved. I’m worried that mistakes were made, and that my teeth will still need a lot of work after tray 14. Which brings me to the refinements: I’m sure my ortho said, at the start of my Lite treatment, it included up to 14 refinements if necessary. But now she says it only includes 2. Do I have a right to ask for more?
