Possible umbilical hernia? Anybody have experience with this?

Hello all! I'm 33 weeks along with our rainbow baby girl, second child. I'm carrying all out front (as I did with my son) and believe I developed diastasis recti after him. I began doing squats and stretching daily and have noticed pain around my belly button and it's getting worse. I can almost see a protrusion where my belly button is and getting worried, I don't see our midwife until Thursday and didn't want to bother them. If thats what it is would there be restrictions for working? My job is very physical and I will be working for 5 more weeks. Thanks for any and all advice ❤️❤️
