Answer
You may have an umbilical hernia. This may cause it to protrude when you cough or laugh and will not show up on a sonogram.There is not much you can do at this time. After the delivery of the baby, a surgeon should evaluate it and see if it is, indeed, a hernia, and whether it should be repaired or not.
