The 32-year-old has been traveling the world with boyfriend Kanye West (Paris, Rio, Paris again), but the jet-set lifestyle she's been leading has reportedly taken a toll on her body.

'Kim started feeling ill on the plane from Paris, and called friends as soon as she landed,' a source told New York Post's Page Six. 'She was rushed to her doctor Tuesday night in tears. She thought she was having a miscarriage.'

Fortunately, the doctor who checked Kim ruled there was no miscarriage and released her. He did, however, tell the reality maven she needs to dial down her hectic lifestyle.

'Kim's not respecting her pregnancy,' the source told the Post. 'She's running around, working out seven days a week. She's working with two different trainers to control her weight.'

Kim is four months along with the baby, who's reportedly a girl and due in July. Kim recently started blogging about mommy-hood and though publicly claimed she wants to become more private, but since West announced they're expecting, Kim has been a contant fixture in the spotlight.

The major scare is noticeably absent from Kim's Twitter feed, so maybe she's heeding her doctor's advice, after all..
