Time for more information? Kim Kardashian opens up to sister Kourtney about the possibility of using a surrogate to carry her next baby on Keeping Up With the Kardashians' Sunday, November 13, episode, as seen in a sneak peek.

The E! unscripted series' preview clip shows the siblings in the car as Kourtney, 37, asks her younger sister, 36, whether she and husband Kanye West would turn to surrogacy if they decide to have a third child. Kim and the rapper are already parents of daughter North, 3, and son Saint, 11 months, and Kim has previously spoken out about the toll that her grueling second pregnancy took on her physically.

"Obviously, I do want to have my own baby, but I feel like I truly don't know if my body can handle it one more time," Kim says in the clip. She adds that she would have constant questions for the surrogate mother during the pregnancy: "Like, 'What are you eating, what are this, what are that?'"

Kim continues to the camera, "There's just a lot of fears I have about surrogacy, and a lot of unanswered questions. I just don't have the information on it — I don't know how I'm going to feel about it. I never have given it that much thought — it's just something that does concern me."

However, Kourtney sees a certain silver lining in surrogacy, namely that it could allow Kim to keep her private life private: "If you use a surrogate, nobody has to know the whole time."

Watch the clip above. Keeping Up With the Kardashians airs on E! Sundays at 9 p.m. ET.
