Exact the same way I have and i don't get it either like you said they said babies don't have much space but seems like mines does and this Friday I will be 39 weeks and she moves so much and hard like she will come out and sometimes it hurts how she puts so much pressure and pushes with her legs or feet's into my stomach, her is head is down already...and I am feeling so big I kind of am but I don't know if she will continue growing more for the next week or so I really don't want that bcuz she is big already ...I was 36 weeks when I got my last ultrasound and she was already 6lbrs+ 8 oz I know they stimate the weight but I feel she will be big ...
I think that some women experience less movement but Ive never had a decrease in movement further into any of the 3 pregnancies ive gone through. My kids actually seem to be way more active the further I get. Im 30 weeks and i get karate chopped ALL DAY LONG! Lol
