No. Any blood is not normal, unless it is from external sources such as a tear in the anus from oversize stools or something like that.
I encourage you to visit a medical professional to assess your condition before taking any more enemas or colonics.
Also, to achieve maximum benefits from a coffee enema, you should take one or 2 cleansing enemas (1-2 quarts warm tap water or saline solution) beforehand to empty fecal waste and toxins from your colon.
