Oh goodness. That must have been a big surprise! Ok so yes girls are notorious for being very active - and possibly more so when they are on heat (which is every four days), so you might see a pattern to her behaviour. The "aroma" is probably when she is on heat as well.
However many owners of female hamsters say they can be very affectionate as well and actually prefer them to boys. Although boys do have a reputation for being a bit "lazy" they can also be so shy that they aren't very interactive.
At the end of the day though each hamster is an individual! They all have their own personalities. I've had a very mavetick super active boy before as well
I think just take it slowly - it's still very early days. At two weeks she is only just beginning to settle into her cage and might not feel ready for handling just yet. I would keep a diarry of her behaviour and you might spot which are her "heat" days from that - ie days when she is a bit maverick or hyperactive.
The nipping sounds like a combination of fear and maybe cage aggression as well. Females do tend to need a lot of space and enrichment. Give her lots of cardboard to shred! Toilet roll inner tubes, cardboard egg boxes etc. And plenty of substrate.
If she's going a bit stir crazy she might need to have out of cage time daily, but I would start with the bathtub or playpen and don't try to handle her straight away. Have a look at the taming guide on the home page

I'll link it below.
The key at first is for her to become familiar with, and trust, her new humans. So talking to her through the cage, and offering treats through the bars is a good start. Then maybe try and start slowly with the taming guide.
It's frustrating, especially for children, when they want to handle the hamster, but you'll need to go at the hamster's pace!
Also there might be better times of night for out of cage time. With our first hamster (who was male) he was super active and wanting to run off between about 6pm and 8pm. Between about 8pm and 9pm he was quite dopey and would just go to sleep on you. By 10pm he was off again and incredibly fast - in his night time mode!
Hand taming a hamster can make life with your hamster very rewarding. Suddenly they will sit on you to be stroked or even go to sleep on you, and will be very easy to handle. It can take a bit of time and patience initially. Ask more about...
