I am Number 4
Rachel Berry doesn't get pregnant at all in Glee. It's Quinn Fabray who gets pregnant in Season 1, episode 4: Preggers.
If you look up Glee Wiki and type Season 4 it will tell you
They ( Rachel - finn - Kurt - Quinn - Santana - mike - puck ) aren't going to be in new directions but I believe some will still be seen.
Season 4 of Glee hasn't even premiered yet, so at the moment, no :P
Season 4 airs on September 13th
I think it is called 'preggers' ep 4.
Yes
Yes.
Season Four of Glee aired between September 13, 2012 and May 9, 2013.
It already has, they are now on season 4
no, there is still going to be a season 3 and a season 4.
