Itch everywhere?

Im at 37 weeks and 2 days, and suffering for bloated/water retention legs. But what's with the itch? It's all over my body! Its all over my legs, arms, stomach and i cant deal with this itch. I scratch till it bleeds. Is this normal? I never had any allergy..#1stimemom #pleasehelp #firstbaby #advicepls #itchypregnantbody#pregnancy
