Hi, I am 39weeeks pregnant and for the last few weeks I have associated this itchiness around my belly button as streaching skin. I have put cortizone on it because it itches so bad that i don't want to scratch my skin off. My OB said that it was apart of my pregnacy mask to have slight discloration of my skin just in the belly area. He also said if it blisters then it might be shingles. No blisters just itchy skin. I beleive it is PUPPP. It's my first child, a boy, and I have had a healthy pregnancy until this itchy belly.
