Why can you not feel movements on third pregnancy at 17 weeks?

At 17 weeks of pregnancy, some women may not yet feel fetal movements, especially if it's their third pregnancy. This can be due to factors such as the position of the placenta, which may cushion movements, or the mother's body having become accustomed to the sensations of pregnancy, making them less noticeable. Additionally, fetal movement can vary significantly from pregnancy to pregnancy, and some women may simply not experience it until later. It's important to consult a healthcare provider if there are concerns about fetal movement.
