Has anyone had umbilical repair surgery as a child?

I'm 32 now and almost 19 wks along.  I've been reading posts on women who have in the recent past had umbilical hernia repair before getting pregnant.  I, on the other hand, had my repair surgery when I was 9 years old.  I've never had any issues with it but my stomach has never had to stretch like this before.  I'm a little nervous but my OB hasn't really addressed it yet. I'd love to hear from anyone who's had or heard of a similar experience.  Thanks!
