How do I know if my Hamster is pregnant?

Question

I just got her a week or two ago. I don't know what kind of hamster she is but she lives alone. When I got her at the pet store she was in a cage with at least 5 other hamsters, most of them male. She has had a rapid weight gain in the past two days and I'm not sure what to do. I read that most hamsters who are pregnant don't like to be held but she doesn't bite me (except for once or twice), although she does run from me when I do try to hold her. She has been nesting in different areas of her cage where she hoards a lot of her food.
