PUPPPs

Abby • Current mommy and expecting TWINS
Okay, so I was sitting here watching cartoons with my son, and started scratching my stomach and at first I didn't realize it and after a few minutes I thought what he heck is making my belly itch so bad? So I looked and my whole entire stomach is blotchy. Not raised from the skin but just looks as if there is a rash covering my whole stomach. 
You can't see it too well in the picture but very well in person. Anyone know if it might be PUPPPs?
