candyapplez, 2 weeks ago I had a NST where they just couldn't get a good reading on his heartbeat. My doctor made me go to the hospital across the street so they could test me on the big machine instead of just the little one in the office. We passed that one. Then, last week, it was really hard to hear his heartbeat and he wasn't moving as much as usual, though they didn't make me go to the hospital.
My little guy just doesn't like the test, and he runs away from the monitor if he can. The ultrasound tech said some babies are like that. Today, I had a protein bar and plenty of water right before the test, and he was bouncing around, kicking me, and letting us hear his heartbeat. Everything looks OK.
Take care of yourself, and hopefully at your next NST everything will be fine.
