support for herniated umbilical?

Jill Wheat

I have a small herniated umbilical & am wondering about ideas of how to give that area extra support at 21 weeks pregnant.  I have been fighting a cold that has lead to upper bronchial irritation making me cough frequently and hard.  This is creating issues for my umbilical area with the extra pressure from coughing............and baby.  Any ideas for a belly button support?
