can i get a second copy of my expungment?

I'm not sure what you mean by that, but I assume you are asking if you can get a second certified copy of your expungement Order.  This is why people should use a lawyer - if you don't keep a certified copy you frequently can't get another because the Court destroys its file, generally 30 days after the Order.   If you have a certified copy you can usually get more copies without re=filing, although if you do the expungement properly you won't ever need additional copies.  This is exactly why people should not do expungements without involving a good lawyer.
