Is this appendicitis?

My stomach has cramped a lot today. Around 6:00 this evening, my right side and the area around my bellybutton started hurting. I feel nauseous. I'm bloated. And my stomach feels slightly harder. When I cough or move my right leg, my side hurts more. And I'm also having rebound pain. The left side of my back is hurting. I don't have a fever. I haven't thrown up or anything. I do have some diarrhea (TMI sorry). The pain in my abdomen was worse earlier. It doesn't hurt as bad now. Is this appendicitis?
