If your temp is a bit low (not all thermometers are accurate), they might be several days behind hatch date. It's hard to wait, but I've had them hatch when I really didn't expect it. There really is nothing you can do to help until they are pipping - if they don't do most of the work, they will just die if you try to help them. I find hatching both fun and stressful, no way around it, I always loose some of them and sometimes most or all of them. On the plus side they are so adorable that I just do it again the next year!
Are these your eggs? Were they shipped? I've had dismal luck with shipped eggs, their air cells are usually not intact and they have a terrible time if they make it to hatch, because the air cell doesn't always reform properly and they can't breathe to work their way out.
However, the movement is a good sign and can start days before actual hatching, which can take a couple of days after they start to peep at you. Darn it's hard to wait!
