Condolences and positive messages continue to pour in for Chrissy Teigen, who announced on Thursday that she had lost her son due to pregnancy complications. 

"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," Teigen wrote on Instagram and Twitter. 

"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," she added.

Fans had followed the model, actor and author's journey through her third pregnancy with husband John Legend after the two announced the new child in his music video for the song "Wild," according to Billboard. The couple have two young children, Luna and Miles, and Teigen excitedly tweeted about the third over the past two months. 

But earlier in September, Teigen's doctor put her on bed rest and on September 28, she tweeted about being hospitalized. On her Instagram page, she wrote about having to undergo two blood transfusions because of excessive bleeding. 

She initially said that her and the baby were OK, but then on Tuesday she tweeted about some scary complications. 

But early Thursday morning, she announced that the baby had not made it, sharing a photo of her in the hospital and one of her with Legend.

"To our Jack – I’m so sorry that the first few moments of your life were met with so many complications, that we couldn’t give you the home you needed to survive.  We will always love you. Thank you to everyone who has been sending us positive energy, thoughts and prayers," she wrote.

"We feel all of your love and truly appreciate you.We are so grateful for the life we have, for our wonderful babies Luna and Miles, for all the amazing things we’ve been able to experience.  But everyday can’t be full of sunshine.  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," the 34-year-old added.

Legend tweeted his love for his son.

Many people online thanked Teigen for being open about what happened to her and commended her for speaking out on a topic that is often discussed only behind closed doors. 

The New York Times noted that in recent years, public figures have been more public about their challenges with pregnancy. Former First Lady Michelle Obama wrote about it in her memoir Becoming and Beyoncé has also spoken about it. 

“What nobody tells you is that miscarriage happens all the time, to more women than you’d ever guess, given the relative silence around it. I learned this only after I mentioned that I’d miscarried to a couple of friends, who responded by heaping me with love and support and also their own miscarriage stories,” Obama wrote in her book.
