I've been thinking lately about purchasing an exercise ball to replace my desk chair at work. My co-worker did this and I tried hers out for a while. It really helped my posture and made my back feel better. My only concern would be that the occasional bouncing would be bad for baby.
Have you heard anything bad about pregnant women using these as desk chairs?

I have this problem, and the counter I work at is so tall that I can't find that will remotely fit my needs.
I have a similar ball with a base in my office. My mom bought it for me because of the long hours I work my lower back would get really sore. It definitely helps and the one I bought you could purchase based on your height (the size of the ball varied).
However, if anyone is trying to work their core muscles, the ball with the base doesn't do that. It only relieves the pressure off your lower back and helps your posture.
