If your concerned u may want to start counting movements to ease your mind. Lay on your side and count everytime baby moves. Anything less than 10 in 2 hrs, call your Dr. (correct me if I am wrong about the amount or time ladies, I am just going from memory).
All sounds normal to me :) I'm 30 weeks and my lil girl has her active and quiet days. Today she has moved but not much. I think as long as your feeling movement everything is good.
I thought the same thing but then i was told that he is getting bigger so he has less room to make the big movements like before. He still gets a couple good ones on me don't get me wrong, but not as many as he did before.
If I call they say as long as your feeling something that's fine but she's no where near as active as she usually is.
It's probably nothin but I'd go get checked. Better safe than sorry. Good luck
