Chrissy Teigen and John Legend Suffer Pregnancy Loss

People – Chrissy Teigen and John Legend are mourning the loss of their son one month after announcing their pregnancy.

The couple — who are parents to daughter Luna Simone, 4, and son Miles Theodore, 2 — shared the sad news on Wednesday, revealing that her bleeding couldn’t be stopped, “despite bags and bags of blood transfusions.”

“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, 34, wrote in a lengthy and emotional Instagram post.

Following her Instagram post, Teigen tweeted, “Driving home from the hospital with no baby. How can this be real.”

In September, Teigen was put on bed rest and eventually hospitalized due to excessive bleeding from her placenta. She recounted one ″scary morning″ on Sept. 29 after receiving blood transfusions when she experienced a ″huge blood clot.″

Sharing an ultrasound of the child on Sept. 24, Teigen applauded him for ″working so hard,″ writing at the time: ″Hi my sweet strong boy. You are working so hard, I promise it’ll be worth it!!!”

As part of Legend’s “Wild” music video, the parents revealed the surprise pregnancy back in August, with a source telling PEOPLE at the time that Teigen ″never thought it would be possible for Chrissy to get pregnant naturally″ and called the pregnancy a ″miracle.″
