So I don't really pay much attention to my arms but just happened to look down and I seem to have hives on my right and left inner arms?? I'm 5w2d...third pregnancy but the first two were losses. Now I have read when u have super high hcg levels this could happen? I could be crazy I don't know but at the er on Friday night I was just 5 weeks and my levels were 12,590! Tia!
