macbook pro mid 2012 doesn't pull in dvd's
A week ago, i tried to insert a dvd and when i put in the slot it didn't went in. I had to push it completely in for the laptop to read it. Once it took it in, it made like a rough sound trying to settle in its place. It never happened before. It reads the dvd's fine, what can-should i do? I live in Puerto Rico and i don't have applecare.
MacBook Pro (13-inch Mid 2012), OS X El Capitan (10.11.4)
