Kim Kardashian experienced a miscarriage scare this week as she rushed to the hospital on Tuesday night after returning back from Paris Fashion Week.

"Kim started feeling ill on the plane from Paris, and called friends as soon as she landed," an insider said. "She was rushed to her doctor Tuesday night in tears. She thought she was having a miscarriage."

Fortunately her worry was "a false alarm" however doctors did reportedly tell her to stop overdoing to slow down and get more rest.

"Kim's really scared - this has been a wake-up call that she really needs to slow down and take care of herself. Friends are telling her to lay off the high heels and the high fashion," one source told Huffington Post.

Kardashian seems now finally accept the fact that she needs to slow down. As she even stepped down her excessive gym workouts, that was to keep her famous figure as fit as possible during her pregnancy.

Khole Kardashian shared on her blog Thursday to thank fans for their support and to clear up the speculation about the baby.

"A lot of you have expressed concern in the recent hours about Kim, and I just wanted to let you all know that mommy and baby are doing fine and just taking it easy right now," she wrote. "Thank you so much to all of our wonderful fans and loved ones for your concern and support. We love you!"

The reality star expressed her thanks on Twitter, "Thanks for all the well wishes, I'm doing fine! Just resting...have a good weekend. Love you guys!"

The four-months-pregnant reality star showed no slowing down before this incident because of her busy schedule, the divorce from Kris Humphries and move.

"She's been working a lot and with the divorce, moving, etc., [she] just needs to take a little rest," the insider told "E! News."
