For almost a week now i have noticed my stool has had that ribbon shape to it. the first stool out is closer to normal shape but everything after has that ribbon shape. no blood, no pain. anything to worry about?

Formed stool and ribbon stool are both normal. the softer the stool is, the more easily shaped it is while exiting the anus. (thus the ribbon shape). This may reflect improved hydration or increased carbs in your diet. Try increasing your fiber intake for better formed stool. Watch for stool that is comprised of little balls as that can be indicative of dehydration/constipation.
