I’m 35 weeks today and the past week I’ve been having less movements. She’ll still move around but fewer times. I’ve been going to NST 2 times a week for pre term and they always have to use this vibrating thing to wake her up. They don’t seem concern but I think it’s odd? She went from doing flips and big stretches to just a small kick. Sometimes I feel like there’s nothing inside me like it’s empty...Is it normal?
