Tree stump shaped umbilical cord?

Alea

Went in yesterday for my anatomy scan.. baby girl is growing and tech said everything that was important is growing like it’s supposed to but I have to go back next month because her umbilical cord blood vessels aren’t in the “normal” J shape? It has the main J shape but it kind of branches out like a tree almost. Dr said it could be nothing, she’s just never seen it before. Anyone ever experience this?
