I still really have my doubts.

As a baby, her YB should be more noticeable than as she ages. I was looking for pictures of my low expression Yb male, but it seems I must have deleted them after I sold him.

I believe if it were me, I would make breeding plans for her as if she were a normal, and if she surprises you then great. But if she doesn't prove to be YB, then you won't be dissapointed.
