I think it's okay....baby moves around a lot and you may feel it on one side vs the other. For some time my baby was head down and I felt a lot of movement in just the middle....now it's lying on it's side and I can feel most of the movement on the right side ( think that's where it's legs are now). I wouldn't worry too much about it.
I feel the baby move mainly on my left side and in the middle of my stomach. Barely any movement on my right side. It think it's normal and it all depends on the position of the baby.
Same thing I feel the baby only on one side. She's lying to her side so her back is on the right and her little legs and arms on the left. It's normal.
I agree with Stacey--the CNM was able to feel his position, his spine running down the right so his little limbs all face the left, where I am feeling all the kicking. To test the theory, try lying down and feel around on your left side, you should feel more firmness where his back is and softer where his limbs are.

I have had the same thing. I tend to always feel movement on my right side and rarely on my left. When I went to see my OBGYN she did an ultrasound and I mentioned it to her. She took a look and showed me how he was lying. He is head down, bum up, and his legs are curled up so his feet end up on my right. So that is what I feel a lot....his little feet kicking and kicking. So, I bet you are feeling the same thing.
Take care!
