Def try music,when my princess isn't moving a lot and I'm used to her moving I play upbeat music while laying down and then she moves a lot! I'm sure she is fine,I've heard this is the stage where they begin to develop sleep patterns so maybe she is sleeping a lot
She might just move around a lot when your sleeping.
Try laying on your left side and play some music on your belly, make sure the music has base lol
Im sure she'll move, even if it's a little squirm or flutter (shes okay)
If your placenta is in the front, it can make it harder to feel.
My Princess moves a lot, but mostly when I'm lying down or after I eat, you can try music too, that may get her going ♡♡♡♡
Try drinking something cold or sweat, then either sir or lay down. If she still isent moving much I'd call the doctor. Best if luck
