It is important to monitor your baby's movements throughout your pregnancy, as changes in movement patterns can indicate potential issues. At 29 weeks, you may have an anterior placenta, which can sometimes dampen the sensation of fetal movements. However, if you notice a significant decrease in movement or no movement at all for an extended period, it is essential to contact your healthcare provider immediately. They will likely recommend monitoring the baby's heart rate and may perform additional tests such as ultrasound or non-stress tests to ensure the baby's well-being. Remember that every pregnancy is different, and if you have any concerns about your baby's movements, it is always best to consult with your healthcare provider for personalized advice and guidance.
