I'm pretty sure that if Nick fathered the child in Adalind, that she'd be the mother just as much as Uther Pendragon was King Arthur's father. To reference, King Arthur was conceived while Uther was magically disguised (Merlin did it for him) as Igraine's (Arthur's mother) husband, the Lord of Cornwall. That, and conception doesn't happen automatically, it would take a bit after Adalind transformed back into herself for her to become pregnant from her encounter with Nick.
