How long Will it pocket for my hamster to be pregnant?

I've had my Female and male hamster together for three days so far. When do you think the girl will be pregnant?
You didn't give us enough information. Is she easy, is she on birth control. Was in attendance alcohol involved. Does the males right ear curl down (this means he's gay)? You got to consider alot of these scientific variables.
Do you know your animals? ?
it depends on what hamster is it? a syrian hamster should only be introduced and never moved out together for 3 days .. while in dwarf hamsters if they are left together probably she might be pregnant. The gestation term for Syrian Hamsters is 16 days. Dwarf Russian Hamsters, Campbell’s and Chinese Hamsters is 18 – 21 days while for the Roborovski Hamsters 23 – 30 days. http://hamster-club.com/reproduction.asp

Answers:    About 15- 19 days. Also be certain to put extra bedding and food and SEPARATE THE MALE HAMSTER. DO NOT DISTURB HER OR SHE WILL EAT HER BABIES. Just be sure to leave the feminine hamster alone during these 15-19 days, or she might be nervous and eat her children. When i say walk off her alone, i mean it, don't even touch the cage.
