Do i have Appendicitis?

ive been having pain on the right side of my stomach. i just finished my period a few days ago. the pain comes and goes. its sometimes lower than the belly on but sometimes its a the op. it sometimes goes to the left side too. this started last nite wen i tried to fall asleep. i dont know if its appendicitis? should i go to the hospital? it comes and goes but its been about the same measurement of pain, it hasnt increased. when i press down whenever it hurt it either does nothing or makes the pain go away. help? quickly.
