Umbilical cord hernia?

Michelle • Momma of 2 munchkins and 1 on the way
After I had my daughter almost 5 years ago I was told at my 6 week appointment I had an umbilical cord hernia. I'm currently 18 weeks and 5 days pregnant and my belly button is starting to pop out but it hurts.. Anyone else have or had an umbilical cord hernia during pregnancy?
