Revealing mistake: Shortly after the fight with Becky, Roseanne asks Jackie to go across the street to get her something to drink, so she can smoke in secret. After Roseanne lights the cigarette and walks near the register, Jackie's plaid coat can be seen in the door's window as she waits for the next scene.
Visible crew/equipment: In a scene where Darlene and Becky are in the kitchen, you can see the microphone above them for a couple of seconds.
Continuity mistake: When the girls are at the Lobo Jackie has a long scarf in her hair that moves between having the length of the scarf behind her back and then draped on her front left side.
Answer: Yes she was. When Laurie Metcalf, who played Jackie, became pregnant during the series, her pregnancy was written into the storyline; her pregnant belly is real. At the end of the episode where Jackie gives birth, there is a photo of Laurie Metcalf in the hospital just after she had her baby.
