Hey noni
Everything would be fine honey
If bub is awake as such too thier heart beat can be a little higher than if they were resting.. one minutes jacobs would be 106 was the lowest (around 10weeks) and when i felt him kicking and stuff later in the pregnancy it was up to 170.
If you are nervous or excited it releases adrenaline into your body which the Ob told me can sometimes get the baby "excited" too.. in turn causeing the higher heart rate. All they really hear every waking moment is mummies heart beat so it would get them going a bit when yours is going heaps fast.

Good luck honey and take it easy ok!!
xoxo
