I only feel mine move ever time I drink something with sugar in it. But my doc said that is normal I wish I new if he was right because it scars me but what can I do he says that all is well. So the not moving thing seem normal to me.
I would do your kick count, lay down and feel how many times the baby is moving. If in an hour you are not getting at least 10 movments I would call the Dr, or if you are nervious about it just call and let them know, better safe then sorry. My friend noticed her baby was not moving much and they ended up having her come in for the C-section early.
I would call them, if anything just to put your mind at rest, they are there for you xxx good luck let me know how u get on xx
