It is generally normal to feel less fetal movement when you have an anterior placenta, as it acts as a cushion between the baby and your belly. However, if you notice a significant decrease in movement or no movement at all, it's important to contact your healthcare provider for further evaluation. They may recommend monitoring the baby's heart rate or performing additional tests to ensure everything is okay. Trust your instincts and don't hesitate to seek medical advice if you're worried about your baby's movements.
