I think I dislocated my knee earlier today.. Whats My Plan?

[tercet]

I was lieing down on my bed in an awkard position with my leg overhaning a part of my bed. I was about to get up then I realized my right leg was pretty much limp from my knee down. After a few minutes of oww this hurts and moving several positions I heard a little snap. I could finally move right leg and bend my right knee.

Should I worry about this at all? This has never happened to me and it hurt a bit for few minutes I couldnt move my bottom part of right leg below my knee for a few minutes.
