Umbilical hernia?

Does this look like an umbilical hernia?

My belly button has looked like this since about 22 weeks. I didn’t have any concern until my mom recently noted it when she noticed my belly button poking through my shirt. I see the doctor in 2 days so I’m going to ask then but wasn’t sure if anyone else’s belly button has looked like this and or if you have had an umbilical hernia during pregnancy.
