Chicken pox?!

My 6 month old keeps scratching her tummy and crotch and there seems to be small red bumps all over her little booty too 😞 I am very diligent at keeping up with her diapers so she never has diaper rash, even when she has it didn't really look like this! Both of her grandmothers on both my husband and my side had shingles about 2 weeks ago and she was around both of them before they were diagnosed. I'm thinking it may be chicken pox 😔 any other opinions?!
