Could I have appendicitis?

I woke up this morning with quite severe stomach pains. The pain is mostly surrounding the navel area. The pain is not sharp shooting pains but rather just crampy like pain and almost my whole abdomen area is tender when i press in at all or even when i lie on my back. At first I thought maybe it was gas or something but I am starting to think it isn't. I took some IBS tablets earlier this morning and i took a pain reliever and about an hour later the pain subsided for the most part and it was gone for a few hours. However, the pain came back so I took more of the same meds and this time they didn't help. I also ate a medium sized meal and it seemed to intensify the pain a little. The pain is almost to the point where it is unbearable and I am just wondering if it could maybe be appendicitis as the pain seems to be a little more on the right lower abdominal area. I wasn't sure though if the pain from appendicitis can go away for a couple hours and then come back. Thank you for any information you can provide me with.
