My bearded dragon has a slightly yellow spot right next to her arm on her belly. She doesn't seem to be shedding, but she might be. Would this be shedding or the start of yellow fungus?
It's likely just related to the shed. Can you post some photos of her? You can upload photos here https://www.beardeddragon.org/useruploads/ and post them to your thread using the XIMG button when you reply.
She kinda panics whenever she is off all 4 feet so I can't get a good picture of the spot . I only noticed it because she was basking and I saw it by her arm. I can try to get a picture while she is doing that, but it probably won't be as easy to see.
