If you clicked on that link and input your details, the chances are, your account will soon be compromised, so you need to change your password as soon as possible.
I've just received one today .... was yours something like this:
A friend messages you saying you're in a video and there's a link to click. You click on the link and it asks you to log into Facebook. After this, I don't know what happens because the website is a fake website .... if you input your log-in details, you've just given them to a hacker .... so ...... change your Facebook password as soon as possible !!!!
