Do i have appendicitis?

well my right side started hurting a little when i walk but when i lay down or sit it doesn't hurt. After some time laying down watching some tv and stand up, it didn't hurt anymore. i can now walk and do stuff without pain. First i thought it was appendicitis but after it didn't hurt anymore i was relieved. It started hurting on my right side but then it's gone after i lay down. What do you think is this?
