As she shared several previously-unseen photos of her daughter during an interview on The Ellen DeGeneres Show, she revealed: "The pregnancy, I wouldn't really wish that upon anyone. Anyone!"
But she added: "It's all worth it in the end, so I would definitely suffer through that, but pregnancy was not a good experience for me. At all."
TV host Ellen said to Kim: "Women who say that it's a beautiful thing I would think..."
Before the reality star chipped in: "They are lying. They are LYING to you. I'm telling you."
She went on: "(My sister) Kourtney said that, my mum said that. I was literally giving birth and I looked at my mum and I said, 'I'm going to get you a medal. You deserve everything'.
"My labour was easy, but just the whole pregnancy was so... I had a few medical issues, so it was really tough, and I gained a lot of weight.
"It was really hard mentally on me. I think with all of the medical issues - I had pre-eclampsia, which was really tough; I had to deliver early."
However, she couldn't hide her pride in her baby daughter, saying: "I wouldn't take any of it back because I have the most adorable, sweetest baby in the world.
"She changes all the time. One day she'll look like Kanye, one day she'll look like me. It's so crazy. And her personality is so cute. She is really calm and really quiet."
Asked whether she had always wanted to have children, the 33-year-old admitted she, 'always wanted about six'.
She added: "After having her I would have a million."
