Teigen has been clear and honest about her mental health.
She revealed that she was taking an antidepressant to treat the condition.
"Just know that there's a light on the other side," Teigen said. "When I was in the midst of everything, I could never imagine myself on the other side of it. Now, I'm able to look at September, October, November, December, and shake my head at how dark and crazy of a period it was. Unfortunately you can only really do that when you're out of it."
And she has said she will not let it interfere with her desire to expand her family.
"I loved being pregnant," she said. "Maybe I should be scared [of having PPD again], but I don't know. It couldn't be any worse than it was, could it?"
