Pink Urine/Should I be Concerned?

[Fawnspots]

Hello Hamster Central!
I'm not sure if I'm doing this right (the posting), but I have a young, female dwarf hamster who's urine is pink. I've heard that this might be caused by a urinary infection or from beet roots in the food mix. (I've checked and there are some beet roots in her food)
She is very active, bright-eyed and soft-furred. She seems very fit and healthy otherwise. I've only noticed now that I've switched her bedding to white bedding.
If I should take her to the vet I will. I'm just wondering if any of you guys have any experiences like this and if I should be concerned.
Thank you!
