It is completely normal to feel your baby's movements low in your belly during pregnancy. As your pregnancy progresses, you may start feeling these movements lower in your abdomen, closer to your waistline. The sensation of pain when bending down can also be attributed to the growing size of your uterus and the stretching of ligaments supporting it. However, if you experience severe or persistent pain or have any concerns about the position of your baby, it is always best to consult with your healthcare provider for a proper evaluation. They can provide reassurance and address any potential issues or discomfort you may be experiencing.
