Orange pee and abdominal swelling?

[Lemon]

My hammy has peed orange all night (bright carrot colored orange) and her sides are definitely swollen all of a sudden. I called the vet already but they won’t get the message until morning

I’m now freaking out wondering between pyometra or a uti or maybe both bc I heard uti can cause pyometra?

She’s only 2 months old and her health is just disaster after disaster and I feel so sad for her

I’m scared bc of the swollen sides that maybe something has been going on for longer and there weren’t any outward signs to notice (she just had an ultrasound last month and it was perfect)

I just gave her some foods with vitamin c to help out until the vet answers
