Does anyone know what this rash might be? It’s on the back of my arm.

I thought it was ringworm but I’m not so sure since the circles aren’t that defined. It itches and it’s spreading around my arm. I have a little on my stomach on it’s starting up on my thigh as well 😥 I’ve never dealt with something like this so I’ve just been putting ringworm cream on it. Btw it’s raised and a bit bumpy. I’m trying to get to the doctor but probably won’t be able to for the next few days.

Edit: nope. I haven’t eaten anything new or used any new creams or detergents or anything, and I’ve never been allergic to anything in my life.
