I think she has a pyometra couchy - I'm so sorry. She has a discharge you can see on the pictures and her belly is very swollen as the womb is full of pus. It can strike at any age at all sadly and she is going to need spayed if she is to survive. This is quite advanced and you need to see the vet asap.
I wouldn't give her any meds as they are not going to help. Take care handling other hamsters as you could pass on the infection and handling her as the womb can rupture.
I am almost certain this is what it is xx
