What result should I see with my colon cleanse?

I am taking a 15 day colon cleanse and I'm on about day 5 I think? Well not much to report and the stuff I read online shows these hideous pictures of big slime blobs coming out of people. I haven't had that, should I or what shoudl happen? I'm taking a product by Natures secret it used to be called Dr's something I don't know but on the front it reads, "15-Day Weight Loss Cleanse & Flush", is this a good product?

just a feeling of healthier you really, you May lose a few pounds, healthier skin and general better well being
