Following the miscarriage, Teigen took a break from social media - returning today with a heartbreaking blog post, explaining her decision to document her pregnancy loss.
"I had asked my mom and John to take pictures, no matter how uncomfortable it was," she wrote on the website Medium.
"I explained to a very hesitant John that I needed them, and that I did NOT want to have to ever ask. That he just had to do it. He hated it. I could tell."
"But I knew I needed to know of this moment forever. And I absolutely knew I needed to share this story."
Teigen, who has two children with Legend, then defended the backlash she received for sharing the intimate photos.
"I cannot express how little I care that you hate the photos," she said, addressing the reaction.
"How little I care that it's something you wouldn't have done. I lived it, I chose to do it, and more than anything, these photos aren't for anyone but the people who have lived this or are curious enough to wonder what something like this is like."
Teigen concluded the blog by saying she has finally found some comfort in the memory of her son Jack.
"People say an experience like this creates a hole in your heart," she wrote.
"A hole was certainly made, but it was filled with the love of something I loved so much. It doesn't feel empty, this space. It feels full."
