Teigen, who was placed on a 2-week bed rest earlier this month, said she didn’t take it seriously enough.

“I didn’t really know that bed rest was in bed. I honestly thought bed rest was you have to really, really relax, stay home,” Teigen, 34, shared on her Instagram Story. “I thought it could be couch rest. But now I’m in trouble. Now I need bed rest.”

The “Cravings” cookbook author said she’s “just trying to be as healthy as possible” as she navigates her third pregnancy, which has proven more difficult than her first two.

“It’s a bit of a difficult pregnancy. I feel good though,” she said. “I will say I’m probably being punished for talking so much about how great the first two went. I was like, ‘Oh yeah, pregnancy’s awesome!’ But now I get it. I get anyone that thinks it’s not so awesome but very happy to be carrying this baby.”

She’s on mandatory bed rest until next Tuesday.

Teigen and husband John Legend are also parents to 4-year-old daughter Luna and 2-year-old son Miles.
