Ive just notice a thread shooting pain but wanted to put mine on.

The last 2 days ive had this shooting pain which feels like its going from my fanny and shooting up into my tum. It was really bad today and after the shooting pain I had really bad tighening pain all over my tum. I have a ob appointment next wed but was wondering if I should be worried and maybe go to the hospital. I just dont want the hospital to think I am a worry wort.

Please help
