I'm Sha's friend who had PUPPP in my first pgcy. It appeared at about 37 weeks I think. I'm so sorry you're feeling it this early

I actually took dandelion root capsules. I also drank my regular red raspberry and nettle tea. I tried every possible lotion I could find, including benadryl cream and sometimes I would take a benadryl just to try to fall asleep (my midwife's advice). Night time was the worst, b/c I just itched and had no distraction. One of the best quick reliefs was baking soda paste, but it doesn't last long. Also I would put ice on the rash sometimes just to numb it. All of the lotions helped a little, but nothing cured it until the baby was born (and then it was GONE). I used gold bond medicated, aveeno, avon stretch mark cream, vitamin E oil - that is good stuff. A cool oatmeal bath helped some. Hot bath/shower is not advised.
Wish I could be more help

I am just so, so sorry. I did have the rash on my stretch marks on my belly, and also on my thighs. There were a few spots on my arms and back but mostly it was my belly. I have scars from the rash on my belly still, definitely different from stretch marks.
There is a skin irritation that is much more serious that PUPPP - it's important to make sure you don't have that. A search of PUPPP on this forum will bring up threads I'm sure that give more details.
Hope you feel better soon!!
