TMI 23 weeks pregnant and breaking out?

Lily • What goes around, comes around.

So for the last two to three days I’ve been itchy but today I decided to look in the mirror at my back and shoulders and they are covered with red bumps. Anyone else experience itchiness due to this type of thing? Someone please recommend something? Help? I’m itchy and my skin is red and my shoulders and back are covered with bumps and I don’t know what to do, I haven’t changed anything in my house or food diet and I don’t know if this is normal
