Kardashian took to Twitter to tell her fans that she is feeling much better now, writing, "Thanks for all the well wishes, I'm doing fine! Just resting... Have a good weekend. Love you guys!(sic)."
The 32-year-old was admitted to the hospital after she felt she was having a miscarriage as she returned from Paris Fashion Week.
The four-months-pregnant reality star flew to Paris last Sunday to join boyfriend Kanye West at a Givenchy show.
Kardashian has been advised by doctors to take adequate rest during the pregnancy.
