Speaking on Keeping Up With The Kardashians on Sunday, Kim said: "Lately I've been thinking I would love to maybe have another baby.
"But like I had two really difficult pregnancies and really difficult deliveries so getting pregnant again it's something that does concern me."
However, Doctor Crane has highlighted there is a "potential fear" for Kim, who suffered toxaemia - which is toxins in the blood caused by an infection - and endured a "very traumatic" labour when she had North and Saint, which could cause further complications if she was to have more children in the future.
He said: "Here's what I think, your pregnancies, you had toxaemia, you had a retained placenta, very traumatic, we're always worried about the next serious complication. I think the potential fear of the whole situation is legitimate.
"You never know that you might not have the same type of problem that might be more serious this time. You're always taking a little bit of a chance. There are situations where retained placenta could be life and death."
And Kim's 61-year-old mother, Kris Jenner, bluntly added: "You could bleed to death."
Following Kim's consultations she visited fertility specialist Doctor Huang to discuss the possibility of a gestational surrogate.
However the Selfish author has revealed she is "scared" about having a surrogate because she doesn't know if she will love the baby as much as her two children , although she thinks she could keep it a secret.
Kim said: "Nobody has to know. I think my biggest fear is that if I had a surrogate, I just don't know like, would I love them the same?
"That's the main thing that I keep on thinking about, that scares me."
