Girls may have had it, with the first pregnancy at the end I got a umbilical hernia, gave birth was all normal, not really bothered, now pregnant second, 10 weeks, because of strong toxemia probably, again popped up hernia, what is dangerous about it, I'll go see the doctor and tell everything naturally, and how to give birth then, cesarean or natural way?
