When you put on the new brakes did you have to only change the front pads or both the pads and rotors.

I just changed my brakes today and I'm starting to notice a really weird sound when I brake. It's like a grinding sound only when I brake. It's that normal because I just put in new pads and rotors or did I do something majorly wrong and should stop driving all together???
