Ring worm ? Please help ????

Natasha • I just want my rainbow baby 🤕🌈 08-28-15 👼🏻

So like About 3 days ago this thing popped up on my arm picture below

Half of me thinks it may be ring worm but then again normally it's a ring around it. I'm extremely nervous I don't really know what to do. I do have pets , can they possibly have it too? It feels a bit scaly when I touch it and it does itch if I be attentive of it. What should I do or what do ya think?
