Has anyone developed a random allergy while pregnant?? All this week when I eat certain food my mouth starts itching. Also my entire body is itching, I got tested for cholestasis but it came back negative. The itching subsides for a bit if I take Benadryl but I can’t figure out what’s causing me to itch
