Teigen's update comes after she was forced to postpone the release of her third Cravings cookbook.

"Today I had to postpone the cookbook indefinitely and send @AdeenaSussman alllll the way back to Tel Aviv," she wrote on Twitter on September 24, adding that she'd also hit pause on filming her TV series Chrissy's Court.

"Baby cannot do it. I am devastated."

In an Instagram video last week, Teigen discussed some of the trouble she'd run into during her pregnancy.

"Anyway, so yeah it's growing beautifully," she said. "Everything is good, I'm feeling good but my placenta is really, really weak and it's causing me to really bleed a lot."

Last month, Teigen confirmed she was pregnant, revealing her baby bump for the first time in one of Legend's music videos.

"Look at this third baby s--t," she said in an Instagram video. "What the? Oh my God."

Teigen and Legend, who got married in 2013, share a son and daughter: Luna, four, and Miles, two.
