Hello! I had similar success with my first flush which was 3 weeks ago. I passed the same thing you are talking about. It was clear and had veins running through it. It was last summer when I was on an aggressive Colon Cleanse and it scare me to death. I called a naturapath that is familiar with the products that I take (Awareness products) and she said it sounded like liver flukes. He comment to me is this is good, the cleanse is working!
