Rash 😔

Hey ladies !

I'm about 15-16 weeks pregnant and have gotten an extremely bad rash over the last few days! So so uncomfortable and itchy. I called the nurses hotline the other night because I was so itchy and in so much pain, and was told I can take some Benadryl which has helped a bit... but today it's flared up again. It's all over my chest, thighs (back and front) butt stomach and sides.

I've tried pure aloe, oatmeal and baking soda baths, gentle aveeno eczema lotion, aveeno anti itch lotion, calamine lotion. Does anyone have any suggestions that are safe to relieve rashes 😔 I'm desperate
