After you file

So I filed mine on the 7th of February and they started I guess going through them on the 8th, and I still haven't gotten mine, I filed with eic, but what strange to me is that the message you get on IRS to go where it says you're return has been accepted and is being processed blah blah change to your return is still being processed so different words same message and I don't know what that means. Anyone?
