Welcome to the forum. I think what you describe is normal for the time period you are in. You will see different colors and tints, depending on your activity level, even after the catheter is removed. More movement/activity= more bleeding. However, remember that it just takes a couple drops of blood to tint a full bag, so it isn't as dramatic as you may think. Here's a simple way to test for the fire engine red scenerio. Empty the bag, then watch the first urine that starts filling the bag. If it appears to be almost or pure blood, you 'may' have a problem. Also, if it is bright red and collecting faster than before, you may have a problem. If it just appears to be 'more red', there's not likely to be anything unusual with it. Otherwise, I'd just monitor it, as a major bleed is a a rare event. This is just offered from my experience with the bag, if you still are worried, call your doctor or their on-call service.
