Several factors can influence fetal movement, including:
1. Gestational Age: Movements become more regular and stronger as pregnancy progresses. 2. Maternal Activity: Movement may be less noticeable when the mother is active. 3. Time of Day: Fetuses are often more active in the evening. 4. Maternal Position: Lying on the left side may make movements more noticeable. 5. Placental Position: An anterior placenta can cushion movements, making them less noticeable.
