Diagnosed with PUPPP rash

Ra

Does anybody know if I should get a second opinion on an itchy rash I have? At emergency care they diagnosed it as a PUPPP rash but reading about it, it says that kind of rash only develops in your first pregnancy in the 3rd trimester. This is my 2nd pregnancy & I’m in the first trimester.

The soonest my family doctor can see me is Friday but I’m not sure if it’s going to be cleared up by then with the lotion they gave me or if it’s something different.
