Diaper rash?

Alexis

I wasn't sure if I was allowed to put a picture so I didn't do it, but my daughter is 7 months old and I recently just moved. 2 days ago I saw she had bumps on her vagina, on the lips and on the public bone. It looks like hives along with a rash. I have a doctors appointment 2 days from now, but does anyone have any recommendations on what to do before then? It doesn't seem to bother her and she's not itchy down there when I'm changing her diaper
