Is the bump occur? I have experience of itchy skin in 5th month pregnancy, so much bump in my arm and neck. At that time I decided to go to hospital because i cant handle the itching feeling and i couldn't sleep because of that. I remember that bump occur after i'm using parfume and i think its allergic effect. But dont forget to tell the doctor that you're pregnant so you'll get the right medication
