Itchy/ rash/ hives at 11dpo!

Mi

Hello mommas, this was my first unusual symptom when finding out, my whole body is itchy!!! Especially my arm, I currently have bumps and (what looks like a rash on both arms now) it is not fun, has me going crazy. I don’t have an appointment with my doctor till tomorrow. Please any suggestions in the meantime?

I have never suffered with this so I’m not familiar with which lotions are best? Thank you
