Gross out alert: Blood in mouth after waking!?!

I have been having problems with acid reflux as of late, and no appetite for two days, and last night, i went to bed, and woke this morning with blood in the back of my mouth and what looked like a clot mass!. I asked my father about it, and am calling my doctor tomorrow, but does anyone know what it could be, or have been!?Www@Answer-Health@Com
