I've got this too. It's really dry and sore aswell. I've always had sensitive skin and it does get quite dry anyway, but it's really bad right now. It looks awful, I don't know how to get rid of it, I just put moisturiser on it to soothe. Before I was pregnant I would use some steroid cream if it got bad, but don't think it would be a good idea now. I'm confident it will go away in time.
