Two Thirty - S4-E24
Plot hole: In this episode Arthur scams Deacon and several other parents for phony piano lessons because he doesn't actually know how to play the piano.

Continuity mistake: When Carrie starts praying in the bedroom, Doug has his hands together. Camera changes and he has got his watch in his hands. A watch that was not in his hands or on his wrist before, might I add. (00:09:50)
Continuity mistake: In the middle of the night when Carrie finds Doug rolling the ham-n-swiss doobie in the kitchen, he dips it in the mayo, and when the shot changes, there's no mayo on it and he dips it again, then takes a bite. (01:25:00)
Mammary Lane - S5-E5

Answer: To answer the question directly. Carrie and Doug do not have a biological child during the show's main run. In season 3 or 4 finale (cant remember which) Carrie has a miscarriage. Later on in the show they find out Carrie has 1 working ovary. Thus reducing the chance of them conceiving. By the final season, they couple agree to adopt from China and go to collect their child in the show's final episode. While on the flight back from China it's revealed that Carrie is once again pregnant. However the last scene of the show is a flash forward showing that Carrie goes full term with that child and they are struggling with both kids.
