I Am Female. I Had Episodes Of Vomiting And Intense

I am female.
I had episodes of vomiting and intense pain in my chest/stomach. I had a endoscopy and sonogram and it ruled out gallbladder, seemed to be normal. I am still experiencing a feeling of a fist in the middle of my chest and now in the middle of my back. Pain is becoming constant, like a dull ache. What should I do. I have a doctors appointment on Tuesday, should I wait. Slightly nervous.
