Some Spiders display a bunch of wobble and some not at all. Some grow out of it and some grow into it. Stress can also bring it on. It sounds like you really should leave her along if you have only had her for a few days. It is really hard to say. I was super clear to the breeder I got my snake from that I wasn't interested in an animal that was all over the place. I can't tell my Bumble Bee has any wobble at all unless he drops his prey item after constriction. Only then, on a rare occasion, he searches around a bit for it. If you weren't looking for it you wouldn't be able to see it but there are some subtle things. I would recommend leaving the snake alone for a week and then seeing how things look.
