Did I do wrong

I used a Hydrogen Peroxide enama, It was o.k. at first then about 3 hours later I got the runs with stomach cramps this kept on for a couple hours then I started to bleed. this kept on for more than an hour, the blood was full of mucus. My stomach became very tender. The next day when I went it was blood tinged mucus. My tenderness has gotten better. the blood and musus has lessened. Right now I feel very weak, but I am getting better each day.  Did I do some kind of damage or is this an indication of a bigger proiblem.

See a doctor right away, and be sure to bring the packaging and any information about the enema.  This sounds serious.
