Has anyone experienced a rash while being pregnant? When I was pregnant the first time, I got a strange, itchy rash on my stomach and arms around the 7th month and it stayed for about a month. My doctor had never seen it before, and he's been a doctor for about 30 years! Now I am 12 weeks pregnant, and the other day out of nowhere I broke out in an itchy rash all over my entire body! I have no idea what caused it as I had not used any lotions or eaten any different foods that day. I took benadryl and it was gone in the morning. Has anyone else experienced this?
