Do I have Appendicitis?

for the past few days it feels as though i have a knot just to the right of my abs, it feels worse when I hunch over and straighten my back. Since 10:00 today the knot has felt worse, sort of a dull pain, no sharp pain, and my whole entire gastrointestinal tract has been making a lot of loud gurgling noises for a few hours, mostly concentrated on my right side. Is this a sighn of appendicitis?
