Bub's movements did slow down for me in the last few weeks, not so much rolls and kicks, but many more prods. Sometimes I can watch my belly move but don't actually feel the movements cos they are so subtle. Maybe watch as well as feel, especially after a cold sweet drink like the others have suggested.

I would get it checked out though if you are worried. Nothing like peace of mind to make you enjoy these last few weeks. I remember a GF constantly saying her bubs had slowed down from about 33 weeks, and she had a perfectly healthy bub at 39 weeks.

Good luck hun! Your lil person is just getting a bit cramped that's all
