How do I know if my hamster is pregnant?

consult the veterinarian for this, don't try to act foolishly.

I am trying to figure that out myself. I had to have 2 hamsters together for 3 days because had to wait for money to come in so I can buy a cage. I think my female is pg. I knew they were male and female but didn't think it would happen so quick.

My female hamster was as sweet as could be, We had no idea she was pregnant (B-1-G-1) when we bought her. One week later, out came her daughter who was just the opposite -- mean and NASTY !! We had to separate them in fear of the daughter killing her mom !!

you think its a female and a male?? sheesh! Well all i know about pregnant hampsters is that ur not sposed to pick them up cause their so little and it'll hurt the babys.
