She was going to, then caught Puck sexting one of the other members of Glee Club, and wanted to give it back to Terri. She mentioned it in the last episode to Puck, saying Terri might not want to baby if it had some made up (I think) disease that Jewish people only get, after Rachel told her about it to see if Puck really was the father, so she could tell Finn and break them up...
Wow, writing the plot is tiring.
