The 'Keeping Up With the Kardashians' star, who has gained 52lbs, has admitted the past eight months have been horrific but she feels "blessed" to be expecting her second child with her husband Kanye West after struggling to fall pregnant following the birth of their daughter North two years ago.
Speaking to E! News, she said: "I just don't think pregnancy and me really agree with each other."
"You know, it was really hard for me to get pregnant so I do feel really blessed that I am pregnant and, at the end of the day, it is a million times worth it."
"I'm really not complaining, I'm just being honest and being honest about [it]. I hate it. I'm not going to sit here and lie and act like it's the most blissful experience. It's awful."
She said she was anxious about giving birth to her baby, believed to be a boy, next month because he already weighs 7lbs.
She said earlier this week: "He's [the weight of] a REALLY heavy pineapple, LOL! [I have] Anxiety, knowing my baby is so big and I'm gaining a lot of weight. My doctor wants me to manage it better, but it's hard to! I have gained more than I did the first pregnancy. I'm up 52 pounds so far, with six weeks to go. North was just four pounds, so this is new to me. This baby is already seven pounds (sic)."
Meanwhile, Kim Kardashian West doesn't think Lamar Odom will "ever be the same again".
The star admits she fears for her brother-in-law because he has a lot of "communication therapy" to do in order to recover after he was found unconscious at a brothel following a drink and drug binge.
She said: "He's here and he's alive, but to say it's not a long road and to say he's fully better is not the truth either.
"He has a lot of work to do and a lot of communication therapy and having to learn to walk again and to talk again. You never know if he'll ever be the same again."
And despite her sister Khloe previously filing for divorce from the basketball star - something which she has since revoked - Kim insists Lamar will "always be family" to her and her sisters.
Speaking to On Air With Ryan Seacrest, she said: "Lamar is family and he'll always be family, we'll always do what we can to help take care of him, and protect him, and be there for him.
"It's a really unfortunate, sad situation all the way around the board, and I just encourage people to keep on praying because the road is nowhere near over."
