Rash on face 19 weeks twin boys

Kr

I go to the doctor tomorrow but wanted to see if anyone has experienced this during pregnancy. My skin has been glowing until about 5 days ago when this EXTREMELY ITCHY rash started. I’ve been using cortisone cream under my doctors recommendation (I already use two daily allergy medicines - approved for use under pregnancy for allergies). I’m 19 weeks with twin boys. See pics.
