You shouldn't be concerned. Once you get close to your due date the baby starts moving rarely. Because its getting in the position to come out and when the baby is comfy she/he will not move as much. The only time you should worry is when you don't feel the baby move at all for a whole day then you should go to your doctor. But I wouldn't worry much. Everything's fine :)
That's why km concerned because a lot of mons have their baby's moving lije crazy. My baby moves but rare. I don't feel kicks as much cause the baby seems to me smooched. I only feel lije as wave movement. I have an appt Monday I'll for sure be asking!
I have 44 days left and she is beating the crap out of me all the time, I don't think she's going to sleep much. Maybe as the doctor? Count movements and write it down. They always say if you don't feel the baby for awhile drink some cold juice and lay on your left side.
Baby should be moving a fair amount still but bare in mind the space is starting to get a little restricted.
Movement might change from a full on tumble about to more of limbs moving about and kicking
