Do i have appendicitis?

let me start from the beginning: I'm 14, and 2 weeks ago my father had the stomach flu. Last sunday, i had diarrhea, and stayed home from school on tuesday. On saturday, i woke up with HORRIBLE stomach pains, that died down, and after going to the doctor, they said it was probably appendicitis, and if it got worse to go to the ER. it didnt get worse, and ive been functioning since. It still feels painful, but its not like the end of the world. The first doctor today said that it still could be, but when i went to the Pediatric Surgeon, he said that this was left over from whatever i had last week. I still feel like this is appendicitis.
