PUPPP in 1st trimester?

Katie
I had little bumps show up on my stomach, chest, and back a few days ago that were itchy. Now they are all over my body. (Chest, stomach, back, sides, arms, legs, hand). I'm very itchy. When they were only a few on my chest/back, I already had a dr appt and they thought it to be hormones, and told me to try benedryl cream. Now that it's spread so quickly, and benedryl cream isn't helping.. I'm miserable itching constantly. After researching some, it's seeming to be PUPPP, but it's very rare to show up before 3rd trimester. Has anyone else experienced PUPPP in their 1st trimester? Or has anyone else experienced this same thing and found it to be something else? They're like little tiny itchy red bumps. Thanks!
