Why is fetal movement always below the navel?

Patient's question:

No

Doctor's answer:

At 4 months pregnant, the fundal height has not yet reached above the navel, so fetal movement below the navel is normal. There may be a sensation of heaviness in the abdomen, so it's important to pay attention to whether it is accompanied by symptoms such as hidden pain. Generally, heaviness is not felt at 4 months of pregnancy.
