Please help me! Itchy painful rash

Megan

I’m at my wits end! It’s been about 2 weeks now and it keeps spreading. I’ve been to urgent care twice and my OB when it first started and the ER. No one know what it is. I’ve tried what they prescribed me, hydrocortisone 2.5mg, an antihistamine, I’ve also tried calamine lotion and gold bond cream. I’ve tried colloidal oatmeal body wash. Nothing is helping and it hurts and itches so bad I swear I’m going to lose it. I can’t sleep. It starts out as a couple bumps and then speads into these burn like patches. It just started on my ears too after itchiness for a few days. Please help meeee!! First 4 Picture shows from first starting, the rest are right now. Also I’m currently 34 weeks pregnant, my 3rd pregnancy.
