Continuity mistake: When Carrie confronts Arthur about looking in her bag, her bra strap is slightly hidden by her top. Camera cuts to a front view of Carrie then back to behind her. Now her bra strap has moved and is totally visible. Carrie never touched it during this time as we see her hands. (00:12:25)
Other mistake: When Doug is drawing a picture to explain to the nurse why he is there, a man purchases a beverage from the "Hot Drinks" machine behind Doug. The drink is ready unrealistically fast and the man immediately takes a sip from an obviously empty cup. Those machines produce notoriously hot beverages, so if the machine actually worked the man would have scalded himself.
Continuity mistake: When Doug has just shot himself and Carrie calls him at work, he looks back to Deacon before answering the phone. On the platform behind Deacon, a woman IPS employee appears instantly. Also, the IPS staff walking behind them do not match between shots.

Factual error: At Shea Stadium, in Queens New York, Carrie asks Arthur if he want a Coolicoo. Carrie then goes to the concession to buy Coolicoo's and tells the guy behind the counter she can see them next to him. However, Coolicoos don't exist at Shea Stadium. They are only available at Dodgers Stadium in L.A.
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.
