Don't worry, my skin has been like that for ages.
I've got sensitive skin anyway so I think that being pregnant just makes it worse with the skin stretching and probably hormones and stuff dries the skin out more.
My itching was getting that bad I was bleeding with all the scratching. It has calmed down a bit, just try slapping as much cream on as possible.
I thought about that liver thing as well, but I read it's the palms of your hands and feet that are signs. xx
