Do I have a serious/minor case of whiplash, or nothing at all?

I'm a gymnast and I was learning how to set because I never do. Yesterday at practice my coach told me to tell her what numer she was holding up before I flipped. I rebounded out of a roundoff, paid toomuch attention looking for her and whipped my back tuck at the last minute. I had a very powerful rebound after landing it and got thrown back to the ground on my upperback which led to rolling onto my neck, it was all really fast. There was a crack up there like a domino effect. I kinda had the wind knocked out of me. I had a headache the rest of the day. Today I have pains, a few in my right shoulder and aches in my upper back and neck, it hurts a little to yawn and look up at something, if i turn my neck for perhaps a headcheck while driving it will on occion crack. It is overall achy together. Im scared!
