Regnant was correct
A queen regnant (plural: queens regnant) is a female monarch who reigns in her own right, in contrast to a queen consort, who is the wife of a reigning king, or a queen regent, who is the guardian of a child monarch reigning temporarily in their stead.
Apparently there is a slight differences in these titles.
Cersei was a queen consort when Robert was alive, then dowager queen after he died but before Joffrey was coronated.
Daenerys means to rule in her own right so she's a queen regnant.
Seems some Conan staffer knows better than both he and Emilia. share
