Itchy rash on belly, sides, and boobs

Amber

I’m 32 weeks and this itchy rash started as single tiny bumps on my belly, my love handles and my boobs about a week ago. They have gotten a little bigger and patchier, and they itch a lot. I drink lots of water all the time and use moisturizers and vitamin E oil everyday. I don’t think it’s PUPPS...those pics look crazy and also I don’t have stretch marks. Doctor just said to take Benadryl 🙄 Any one else getting anything funky going on with their skin??
