Why can't I see my last frame

When I'm animating I click on the next frame and I can't see my last frame

This happens when you paint/ fill in the canvas. Ideally your workflow of creating an animation would be doing the sketches of the frames and then when they are working together paint them. Lines you don't want in there should be erased and not painted out by using the background color. 
Try to erase parts of it and you'll see more in the next frame again ;)
