Itchy rash

Amanda

I’m 8 weeks pregnant and this rash popped up about 4 days ago. I’m itching all over but my back and thigh is where the rash is. Couple spots on my face now too. Doctor said looks like an allergic dermatitis. I also take pretty hot showers. Could it just be I’m drying my skin out? I don’t know what to do. Hydrocortisone cream isn’t working.
