HELP - peggys bleeding!

[fluffymunchkins]

So when cleaning her cage today i found her wheel had dried blood on it.
My first thought was that she may have caught her foot when running. But i then found dried blood in her nesting material aswell!

I looked her over and blood came out her vagina

I looked in hamsterlopaedia and found Haematuria (blood in urine)
I've yet to see if shes drinking but she is acting completely normal. No pain or discomfort.

I think a vet trip will be needed tommorow.
Please give me some advice and any other possible things that could cause it.
I'm so worried, shes old now and any treatment will be a struggle for her, but i know shes a fighter.
