Itchy red skin !!

Ruth
Ladies I am 36+1 wks pregnant . I will have my csection in two weeks . I have been experiencing itchy dry skin for about a week I would say. Is this normal?? This is my first pregnancy. I have itchy skin all over my even my baby bump. Now I have like red spoty cuts on my tummy. Is this normal ?? Now we did purchase a new mattress foam pad for our bed on black friday could that be it ??? Sorry for tmi ok the photo ? Thats my baby bump. My arms are red. I do use dove sensitive skin body wash. I use jergens ultra healing body lotion.
