32 weeks, NSTs start tomorrow bc of GD

Colleen
Anybody have GD and have NSTs? What are they like, what should I expect??
 I guess I'm a little nervous. And today I'm extremely sensitive to movements with baby. Didn't think he was moving as much, so I laid down and within 20mins I had probably more than 20 kicks/movements. Some were bigger/stronger than other, is that okay? Also, whenever I would press on, or nudge my belly within a few seconds he would move. So I think I'm just stressing over these NSTs tomorrow. He's clearly moving, but I'm all nervous today. I shouldn't need to call doctor since he's passed the movement test, right?
And of course, as I'm typing this....he's moving around.
