Jennifer Lawrence was five months pregnant while filming movie about woman experiencing postpartum psychosis

Jennifer Lawrence shares insights on her postpartum journey, filming "If I Die" while pregnant, and how becoming a mother has reshaped her personal and professional life.

Christina Dugan Ramirez is an entertainment writer for Fox News Digital. 

"As a mother, it was really hard to separate what I would do as opposed to what she would do. And it was just heartbreaking," Lawrence, whose character experiences psychosis after the birth of her child, said during a press conference, per Variety. "I had just had my firstborn, and there’s not really anything like postpartum. It’s extremely isolating, which is so interesting. When [director] Lynne [Ramsay] moves this couple into Montana, she doesn’t have a community. She doesn’t have her people. But the truth is, extreme anxiety and extreme depression is isolating, no matter where you are. You feel like an alien." 

Lawrence, who revealed she was five months pregnant with her second child while filming the movie, which also stars Robert Pattinson, said becoming a mom changed her in ways she never imagined.
