I am 7 weeks pregnant, and I woke up this morning itchy. I thought and assumed it was dry skin. When getting dressed, I noticed raised marks like hives. I didn't eat anything I have't had before, and never experience this before. I have these marks on my wrists(both), my hips, stomach area, under where the bra is, behind my knees, and other places I'm discovering as the afternoon goes on. Is this a normal symptom?
