Chrissy Teigen has suffered a miscarriage of her baby boy, following a hospitalization this week for excessive bleeding due to a “weak placenta.”

Posting a series of black and white images on Instagram, she wrote, “We are shocked and in the kind of deep pain you only hear about, the kind of pain we’ve never felt before.”

“We were never able to stop the bleeding and give our baby the fluids he needed, despite bags and bags of blood transfusions. It just wasn’t enough,” she added.

Teigen and her husband, John Legend, announced their pregnancy in August. However, after the announcement, she had to face a few health complications.

In September, Teigen was advised bed rest for a couple of weeks. And in three weeks, she was hospitalized for excessive bleeding from the placenta.

On Monday, the 34-year-old model told her fans that she had to undergo two blood transfusions, although she did not reveal exactly why she needed them.

Sharing the heartbreaking news, Teigen revealed her son’s name.

She wrote on Instagram, “We never decide on our babies’ names until the last possible moment after they’re born, just before we leave the hospital. But we, for some reason, had started to call this little guy in my belly Jack. So he will always be Jack to us. Jack worked so hard to be a part of our little family, and he will be, forever.”

Teigen also thanked “everyone who has been sending us positive energy, thoughts and prayers.” She expressed how grateful she and Legend are for their “wonderful babies Luna and Miles” and for all the amazing things they’ve been able to experience.

“But everyday can’t be full of sunshine,” she continued. “On this darkest of days, we will grieve, we will cry our eyes out. But we will hug and love each other harder and get through it.”

Fans and friends alike expressed their grief, praising her courage to sharing the tragedy.

Busy Phillips wrote, “In awe of your bravery and selflessness in sharing as you have, which is going to help so many women and families.”

“I am so astonished and in complete awe of your bravery. You just made so many women feel seen by sharing this intimate grief,” commented Melissa Fumero.
