I just went took a poop and after I got up I noticed all this blood in the toilet I wiped no blood on tissue help me please?

Hemorrhoid. At your age this is likely a hemorrhoid although of course it could be anyone of a number of other things. You are correct - hemorrhoidal blood is usually red and found on the outside of the stool or in the water - not inside the stool. If there is no more bleeding you are probably fine just waiting this out and letting it heal on its own.
