Is this still orf or something else?

My ewe and her babies had orf 4 weeks ago. The babies are all cleared up but the momma still has a few bumps on her udder. Does this look like orf or something else? The one bump is pea sized and the others look like two tiny bumps.

I don’t know. Keep an eye on it to see if it blisters up.
