Continuity: As Juno is walking into the abortion clinic, an exterior shot shows that there is only one entrance door. The shot of her entering from inside the clinic shows a double-door entrance.

Visible crew/equipment: In the scene where Juno and her friend are looking at the Pennysaver in the park, you can see the boom mic at the top of Juno's sunglasses.

Continuity: The first time Juno is seen at school while visibly pregnant, she is talking to Bleeker who is holding a box of doughnuts. In shots from behind Bleeker the side of the box is white, while in shots from behind Juno the side is see-through, and it continues to change back and forth throughout the entire scene.

Continuity: When Juno is walking to Women Now and runs into Su-Chin, as they talk, Su-Chin's sign is constantly changing position. When they show Su-Chin the first time, her sign is high near her head, then when they show her shoulder you can barely see the top of the sign. This continues for the whole scene.
