Despite taking it easy, Teigen hadn't actually been spending all of her time in bed.
"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," the mother of two told her Instagram followers in a video on her Story. "I thought it could be couch rest. But now I'm in trouble. Now I need bed rest."
She described her situation as "super serious bed rest times," adding, "Just trying to be as healthy as possible."
Teigen went on to note that this has been her most challenging pregnancy yet.
"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."
Been in bed for all but 5 mins of the last 24 hours. Here til next Tuesday. Lord it’s kind of crappier than it sounds. On punishment for saying the first two pregnancies were easy peasy
