From what I know of the SCD, I think it is similar to an antifungal program/diet I went on. If so, you may be experiencing what is known as "Herxheimer's response". It is an initial die-off of fungus/yeast that may have been contributing to your symptoms. You will feel worse before you feel better. Everyone is different as to when the "die-off" kicks in, and what you may experience. For me it was day 2-5. I felt terrible....flu-like symptoms, major D, lethargy, achiness, etc. You may, or may not be experiencing this. I guess the only way to tell is to see if your symptoms improve in the next week or so. I would not give up on the diet. It may take a long time before you can tell if it will help you, or not. It is not a quick fix. It took you a long time to get sick. Can't expect miracles overnight, unfortunately. Even 4 weeks is not enough time. Do you have any symptoms beside the D and bleeding? And, have you thought of taking natural antifungals while trying this diet, or having your doctor prescribe Nystatin to quicken your results, in case it is a fungal condition you have? Good luck. I really hope this will be something that works for you!
