It is completely normal to not feel your baby move at 17 weeks of pregnancy. Every pregnancy is different, and some women may start feeling fetal movements earlier or later than others. The fact that there were visible movements on the scan indicates that your baby is active and developing well. As the weeks progress, you will likely start feeling those first flutters and kicks. If you have any concerns or if you don't feel any movement by week 20, it's always a good idea to consult with your healthcare provider for reassurance.
