28 weeks - softer fetal movement

I’m about 28 weeks. From weeks 24+ I was getting definite kicks and basically all I had to do was lay down and I would get 7-8 little pings.

This last Saturday I went into L&D due to reduced movement. I was feeling movement, it was just less strong and frequent. They hooked me up to the monitor and said everything was beautiful. He also started moving there. Lately, I’ve been getting softer movement that’s more like nudging then kicking and I sometimes won’t feel it at all but can see my belly twitch/move from the outside. Doctor said this could be due to baby getting bigger, or baby being flipped inward, but as long as there’s 3 movements in 30 min or 6 in an hour not to worry. Anyone else experience a change in type of movement at this time?
