but my file size just keep getting bigger as i make more changes during my animation ...does anyone else have that problem
I can't say I have that issue...
File sizes are meant to get bigger; as long as you keep creating keys, and continue animating, that's just more information for Maya to keep track of.
Are you experiencing this lag while playing back your animation? Or just while navigating around in your viewport?
If it's the former, that is a memory-related issue. If it's the latter, I cannot imagine why lag might be occuring.
One the side about construction history:
Construction history is self-explanatory by name; it's history of construction operations that have been used while you create a model. You should delete it before doing ANY animation work, though, to be safe.
Once you begin animation, you shouldn't do any more modeling work (and thus, not have any more con. hist. to delete).
