Radar Online reveals that the 33-year-old can't go a day without vomiting and she needs to carry sick bags with her wherever she goes.
"Khloe is sick all the time and she's hating it," a source told the publication.
"Morning sickness has really taken the fun out of the pregnancy."
The source adds that she "looks sort of green too" and she "can't even drive across town without puking".
The reality star is reportedly expecting a boy with her NBA star bae, Tristan Thompson.
Here's hoping the rest of her pregnancy won't be as much of a struggle!
