I am waiting for DH to get home in an hour and i am going to go to the dr. but i thought that i would ask inhere first!! Yesterday i noticed a itchy blister type rash on my chest then today my sil said i have it all around my back as well, she can see it above my shirt. It is itchy but not really bad!!!!! Now i am home after getting the kids i can feel it all around my back and more on my chest!!!! I am 25 weeks pregnant has anyone else had this????? What could it be????? Never had this before!! They actually look like little clusters of blisters!!!!!!!!
