They can get pregnant by age 5 weeks. When did you get her? Hamster gestation is 15 to 21 days. Does she live with another hamster? Make sure that its another girl, and not a boy. Also, they will need separated if she IS pregnant, and should be separated regardless if they are Syrian hamsters.
Just follow the advice in the following links. If you want, you can even join the forum and ask advice.
I noticed your user name... I hope you are not intentionally trying to breed Violet. At her age she is still not fully developed enough to carry a litter, and will probably have problems, or cull the entire litter. Also, if you don't know her or the father's genetics, then the litter could be born without eyes or teeth. That's a death sentence for every pup. Finally, we already have more hamsters than there are homes, so home breeding hamsters is very irresponsible.
A hamster can get pregnant between 4 and 8 weeks of age. A few are fertile at 4 weeks, more at 6, all by 8 weeks at the latest. This means that your hamster is pregnant if you spot some funny behavior.
