Is my Hampster Pregnent?

Question
My hamster has made a large nest/burrow and she's been hiding in it for acarolina.rr.com while now. I wasn't home and my sister let her "play" with her and i have checked different web sites but i don't know if she's pregnant or not. What is a clear sign that a honey hamster is pregnant? This is kind of urgent write back soon please! Thanks!

Answer
If she does not come into heat four days after the encounter she could be pregnant. If she does not come into heat within eight days of the counter she is most likely pregnant, or in a false pregnancy. If she is pregnant she will have the babies in 16-18 days.
