TMZ reported Thursday that Kim Kardashian made an emergency visit to the doctor after feeling "severe stomach pains" on a Tuesday night flight from Paris to Los Angeles with boyfriend Kanye West.
According to The New York Post, the 32-year-old reality star feared a miscarriage and "rushed to her doctor in tears."
After the doctor assured Kim that the miscarriage scare was a false alarm, he warned her about working and exercising too much during her pregnancy.
"She's been working a lot and with the divorce, moving, etc., [she] just needs to take a little rest," a source told E! Online.
Though there's no word yet from Kim's camp, Khloe Kardashian updated fans on her sister's progress via her blog.
Kardashian and West had traveled to Paris for a Givenchy fashion show and a dinner with Frank Ocean and designer Riccardo Tisci.
