I think you are going to be fine. In my experience seeing sick snakes in clinic, the fluid that comes out of an infected animal is usually thick and viscous, almost like snot when you have a cold. Its almost always pretty obvious when a snake has an RI or mouth rot. Most sick snakes will look as if they are blowing bubbles out of their mouth. I once had a BP with a major RI and you could hear the poor snake cough from downstairs and down the hall.
Sounds like this isn't the case for you.
