The drought - S1-E11
Continuity mistake: When Carrie farts, Big's right arm is over his head on one shot and extended over Carrie's head on the following. Then back to the first angle.
Continuity mistake: Charlotte holds a picture of John John by the upper, part, in the close-up she is holding the left side.
Continuity mistake: After the babyshower, while at the bar, when Miranda drinks beer, Carrie's left arm is either on the counter or down by the side, depending on the shot.
Continuity mistake: When Charlotte says Shayla is her baby-name the woman behind Laney suddenly disappears and reappears between shots.
Continuity mistake: When Carrie is debating whether to go to the babyshower or not, her hair is over both of her shoulders or just over the right one. This jumps back and forth.
Audio problem: When Samantha asks Carrie to give her a good reason to go to the babyshower, Carries says "ok..." but her mouth isn't moving.
Continuity mistake: During the flashback, when the crowd cheers Laney she reaches towards the girl next to her while a man sits behind calmly. A shot later she is moving in the opposite direction and the man has his hand on her shoulder.
Continuity mistake: When the girls are watching TV and eating popcorn, all along the scene Miranda's hand movements are not continuous between shots. Most noticeable when Carrie asks her if she hates the babyshower because it's Laney's, Miranda's hand swaps from reaching the bowl with popcorn to away from it.

Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
