5 weeks, strange rash

I am 5 weeks and have the most horrible sporadic rash! Little bumps that resemble a mosquito bite pop up and they’re itchier than poison ivy! My doctor said it’s dishydrotic eczema and have me a topical steroid but I’m afraid to use it due to being pregnant. Anyone else in this boat? I will also add I was advised to take benedryl but I can’t live my life on antihistamines and sleep the weeks away! #atmywitsend
