Pupps rash?

Amanda

Does anyone know if you can develop the pupps rash after pregnancy? I have a really itchy rash that started on my hands then moved to my breasts now I have huge patches on my stomach that have taken over all my stretch marks and my stretch marks are bright pink now. Its also on my arms.. I'm almost 3 weeks pp and never had pupps during either of my pregnancies but when I google that it looks a lot like the rash I have on my stomach but it dosent say anywhere that it can develop after pregnancy?!?!
