Need answers, this is serious!

I've been doing The Master Cleanse for 4 days. I've been drinking the shakes along with a salt flush and lemonade drink. I never have seen blood in my bowels before I started cleansing! Well today there was blood in my stool along with my poo. Later, I had another BM with this mucous looking stuff along with blood, and that's all that came out. This is scaring me! Has this happened to anyone before? What should I do? Is the psyllium husk and salt flush too much for my system?? I'm SCAAAAAAAAAARD!!!!!!!!!!!!!!
