Need help identifying a movie

Hi! I saw a part of this movie on TV a couple of weeks ago. Unfortunatly I didn't get to see the ending or find out what it was called. I think it was a french movie, but it's hard to tell, because it was dubbed in english.
Here's the little i got of the plot:
There's a young girl living in some sort of closed bording school or something. She's pregnant, but has to hide it. She has a friend with trouble remembering something, I think she had a traumatic experience as a child. There is also two women living at the school, a strict principal type and a warm nanny type.
One day the girl finds some old files of children. I sense there is a mystery of what happened to the children and why the school was closed.

Does this seem familiar to anybody? If anybody could help me with this I would appreciate it very much!

 

Doesnt ring any bells, but sounds like a good movie..

 

Yeah, it seemed really good. The filming was so poetic and the music was this wonderfully haunting choir music, that sent chills down my spine, even though it was 35 degrees celcius outside.

 

I don't know if this is the film, but It might be Au Revoir Les Enfants. I'm not sure if it is or not because I never saw it, but I saw someone talking about it in an older post. hope it helps
