Feeling baby movements below the belly button at 20 weeks of pregnancy is completely normal and expected. As your baby grows, their movements will become more noticeable. It is common to feel kicks, flutters, or even rolling sensations in the lower abdomen. These movements indicate that your baby is healthy and active. However, if you experience any sudden decrease in movement or have concerns about your baby's well-being, it is important to consult with your healthcare provider. They can provide reassurance and address any potential risks or concerns specific to your pregnancy. Remember, every pregnancy is unique, so don't hesitate to reach out for professional advice when needed.
