Just a worried ftm

So i know the movements aren't supposed to change as you get further along in the pregnancy but what if its just a slight change? Im 38 weeks and just have noticed that she isn't moving as much as she used to. I would still call it safe because she'll have the normal 10 within 2 hours when stimulated (cold water, ice cream, coffee) but other than that she's just "chillin" if i call l&d they'll just say she's okay but have you ever had a gut feeling that maybe something's wrong?
