rash?

Sa
Has anyone else had this? I have flat red bumps or small blotches all over my arms legs stomach Chest butt everywhere but my face? I saw something online about pep or pupp but that's supposed to come from stretch marks mine is everywhere not just on my stretch marks.   It's alil itchy but that may or may not be in my head. I haven't worn any new unwashed clothes or eaten anything new. 
Any ideas? I may call my dr if it doesn't clear up tomorrow.
