Nope. The only thing you'll see is the yeast settling to the bottom after it has completed conditioning, and even that may take holding it up to a light.
Foam only occurs when the CO2 bubbles out of solution. Since a bottle is a sealed system, the CO2 stays dissolved until you open it
If you are using plastic soda bottles, the only thing you will notice is the bottles getting hard as a rock between 10-14 days. If you are using glass bottles, just let them sit for 2 weeks, refrigerate one and crack it open, if it foams and it is carbonated, you're good. otherwise, leave the beer alone.
I never noticed anything happening in the glass bottles, I did one plastic just to feel where the processes was at. It worked out because I realized that I put to much priming sugar in when the bottle was hard and looking like it was about to explode. At that point I popped a glass one to taste and make sure.
