Umbilical hernia during pregnancy?!

Haly • 1 angel baby 👼🏼 20 mama to a 1 year old baby girl TTC #2!

So I was walking past the mirror and happened to glimpse at my belly button when I looked I saw a strange looking bulge above my belly button. It is smaller about the size of my fingertip. I looked it up and it said it was an umbilical hernia. Has anyone else experienced this during pregnancy? Is it a cause for concern? I have an appointment on Friday but should i call before that? I’m 36 almost 37 weeks btw.
