Hi, I had that same type of itching in my past pregnancy minus the bumps and my Dr said that it was because of the stretching of the
skin and also from it being
dry. The only thing that said I could do was keep it moisturized and believe me, everything I tried didn't help either. And if you are scratching, it will only make it worse. So, what I bought this time and I haven't started itching (knock on wood) is Palmers products and I use it faithfully.
