I looked into this because I was diagnosed a few months after I had my baby. All of the studies a few years ago seemed to say that her2 was no more prevalent during pregnancy or soon after, but younger breast cancer patients tend to be disproportionately her2+++ and they are the ones who get pregnancy-affected breast cancer. Something like 40% of patients under the age of 40 are her2+++.
