Have it checked out. It could be PUPPs. And if that's what it is.. youre in for a loonnngg uncomfy time.. the only way to get rid of it is to have the LO as PUPPS is a pregnancy rash caused unfortunately by just being pregnant.
Have you gone to the dr for it or found anything that helps stop the itching?
Yup, I got one too don't itch, wet a wash cloth with cold water and just leave it on the party that itches.
