Jaw pops and moves weird when I open my mouth?

Every time I open my mouth, my jaw makes a popping noise on the right side up at the top, and it almost feels like it's misaligned. When I open my mouth, moves to the left. It doesn't necessarily hurt, it's just kind of uncomfortable and annoying. I don't know what's wrong with it. Does anyone have an idea of what could be going on with my jaw?
