Sick Ball Python?? Please help

[Theweinz]

Last week I noticed a little blood in the urine and then again in a poop of my four month old female Spider Ball Python. The blood was bright and fresh, only a tiny bit at the end of both the pee and poop (saw it twice). She fed again, quite aggressively actually, and I waited to see if blood appeared again. Yesterday, after about a week she peed and there was no blood. Today she pooped and it was completely clean too. After the poop She fed again without hesitation. She is active, growing, not irritable, handles well, and feeds. What do you think? I feared a intestinal bug, amoeba or something, but there was no diarrhea, always well formed poop. It could be cancer but she is not slowing down in any respect (at least not yet). Never had a snake do this. I was all ready to take her to the vet, but with clean pee/poop and all other indicator ok I am going to watch and wait. Any opinions or experience with this? She is a beautiful little snake.
