So on three occasions today my mouth has seemed completely full of blood! I've tasted it, popped a finger in to check, and there's definitely blood - completely red saliva comes out. I've rushed to the loo a couple of times convinced my teeth must be all red and Halloween-like, but they actually haven't been, so I'm thinking it must be coming from the back of my teeth or somewhere further back in my mouth.
Has anybody got any idea what's going on here and is it any cause for concern?!
