Why does my appendix hurt?

Since last night (so for about 6 hours now) I've had this pain on my lower right side. I looked it up, and it's right where diagrams show that my appendix is. I can't figure out if it's appendicitis, though, because the pain isn't at all bad. It's just enough to bother me enough that I thought I'd ask. When I push lightly on it or draw my leg up to my chest it stops hurting. I'm 15 years old, if that makes a difference. Is it possible that it's appendicitis? I'm going to tell my parents as soon as they wake up, but I just thought I'd ask here first.
