umbilical hernia

I am currently 21+5 and my doctor told me I have an umbilical hernia my last appointment. she told me as long as it’s not hurting me really bad or causing problems it should be ok until after baby is born and I recover I could get surgery to repair. i’ve had it with my last pregnancy as well but my doctor did not pick up on it so I am a little nervous i’ve have it for to long and it’ll get worse😕 i’m trying to think positive.. she told me if I could push in my belly button then it’s still fine. so I constantly push it in lol. anyone had an umbilical hernia with two pregnancies? how’d it go for you? or just having one while pregnant in general? did you get it repaired after?
