Diaper rash not going away!!!

Amarillys/22🧚🏻‍♀️

My 22 month old daughter has been having this rash almost a week she has an appointment tomorrow but I’m just so stressed it’s not going away (I’m sizing up diaper tonight) I’ve used A&D, mixed A&D with desitin. I haven’t been using wipes for 3 days and it was a slight improvement but it feels like it just keeps coming back raw again ): we’ve been using Huggies since she was born and she never had diaper rashes and now all of a sudden she has this! she had it way worse on Saturday but it’s still like this. We are also gonna try potty training this weekend. I would like to mention she had strep throat almost 2 weeks ago
