I'm currently going through this. Over Easter, my bub didn't move for 4 days (well at least I couldn't feel the movements). I had it all checked out at the hospital, and all is well. But I have to monitor her movements from now on as she went from being extremely active to nothing. They told me to try and get/feel 10 movements per 24 hours. Anything less, to let them know. Maybe keep an eye on how many movements you are getting, so you get a better idea.
