Do the baby’s movements slow down?

My baby has been super active, and he still is, but his movements have been slowing down over the last 2 weeks… I’m 27 weeks now, for context. He kicks 10x in about 20 minutes, but it used to be 10x in 10 min or less. And the movements are slower than they used to be, which I’ve been attributing to him getting bigger and having less space. Should I worry? Is he fine because he’s kicking at least 10x in less than 2 hours? I already see a high risk doctor and have appointments about every 2 weeks, and they haven’t noticed anything alarming, but I’m still stressed 😅
