The producers have been interviewed about Gwen being pregnant, they laughed and said in Series 7 or 8 I think.

That is if they will continue it up to there, but it wasn't the originally plan. They said it is determined on popularity, and I put all my faith into the show being better this season, so there's a high chance that ONE DAY there will be a baby in this franchise.
