Change in baby's movements? EDIT**

After 2 days of her being relatively quiet in there i finally went to l&d to get checked out and of coarse baby decides to have a party in there once hooked up to the machine. Everything is looking good so far.

Im 31 weeks and have noticed baby seems to not be as predictable as she used to be. Anyone else notice a change in movements? She almost seems quieter in there the last few days. Should I be worried ? Should I go get checked? I have a doppler and check on her whenever I feel worried but she used to be so predictable with her movements and now not so much.
