stomach pain

Hi everyone. I didn't know what group to put this in and I thought it was my health.

So I have been having stomach pains lately. It's not gas, nauseous, or cramps (period). It is on my right side. And last night I had it and it was the worse thing. I took Advil and that helped. I did not go to the ER. But I thought it was a kidney stone, but mom told me you would be throwing up and everything. (My mom has had a kidney stone before). So I looked up appendix and they said on my right side and it said that the pain will start out slow and gets worse. And that's what happens to me.

Please help me!!! I don't know what's wrong with me!!! Please comment!!!!!!
