is my hamster pregnet?

Question
My cousin gave me a girl teddy bear hamster,he said she already mated. I dont know if she's pregnet but she is really huge!!

Answer
How long ago was the mating? Hamsters stay pregnant from 16-20 days. You really don't know she is pregnant until a few days before birth when her stomach plumps up really big. I'd realy talk to your cousin about when she mated to figure out if she's pregnant or not.
