Heat rash /bumps

Marie • Hello, my name is Marie, I'm 27 years old and I joined this website the moment I found out that I was pregnant. This is my first pregnancy and I'm praying for a 100% healthy baby boy or girl 😊

It looks like 2 different rashes. (Face)heat rash but around her neck is what's really bothering me. And it flares up sometimes. What can I use?
