is it their child or she had a child with his subordinate who's acting as the king?

as far as i understood, the MC Girly cannot get preggo in the first place (it was mentioned in ch 5(?)) and i think it was another girl (seeing as a lighthaired girl was shown) that gave birth to a child instead, maybe actually subordinates baby (who knows). It was for show, so they have an excuse that she died in childbirth and could take off. I don't think it is her child.
