Appendicitis?

For the past week now I’ve been feeling a burning sensation cramos in my right side of my abdomen. It radiates to my bellybutton lower right abdomen and upper as well. It is very uncomfortable and painful. I have been nauseous. I was maybe worried i was pregnant which I hope im not but it just doesn’t feel like a pain you would get if you’re pregnant. I took 2 test already both negative(i use the pill amd condoms). When i press it hurts more. Also I’ve had diarrhea.Any thoughts??? Pls respond im not sure if I should go to the hospital or not.
