I think your blood is fine. When I do it where I can see it, my blood is as thick as water. But when I put something on the wound and look at it, the blood is thicker. I am not a doctor, but I think your blood is coagulating. If you are really worried, maybe consult your doctor.
I hope you are doing okay with your SI. I'm sorry you are dealing with this.
