Khloe Kardashian was "freaked out" after realizing the "control" a surrogate would have over their pregnancy.
The 36-year-old star has been documenting her journey to have another baby with Tristan Thompson, and she hadn't "put two and two together" about the process.
During this week's episode of 'Keeping Up With The Kardashians', the couple - who have three-year-old daughter True together - met with a surrogate therapist.
He asked: "What are your beliefs about foetal reduction or termination of pregnancy due to multiple pregnancies? Say, the embryo splitting and the surrogate was carrying twins suddenly."
While Khloe said they would be "on board with that", the therapist pointed out that it's the surrogate's body, "so she could terminate the pregnancy with any unplanned outcome".
The reality star later said: "I’m definitely getting freaked out I think as the questions go by just because I, of course, I know it’s her body, my baby, but I really did not put two and two together that that means she has the control whether she would want to, you know, terminate the twin. Me not having control over that outcome, makes me very nervous.
"I mean, I know it’s her body but I still didn’t know it was really her choice and that might be really naive to say but I mean this is a big eye opener.
"I’m definitely second-guessing a couple things. It’s just a little intense this whole Zoom call.”
In scenes filmed in the summer of 2020, she then contacted a surrogacy broker, who reassured her that there were ways to get things in writing to gain more control over the process.
Tristan suggested they simply needed to "find the right surrogate", and Khloe responded: "It’s just releasing so much control.
“First it was being told, okay I would not be able to carry — that took a minute to process, cool. I’ve accepted that. Now I’m in phase two: Find a surrogate.
"I can’t think too far ahead, because this is where I am for phase two, I do think this is the right choice for us, but I’m not going to be rushed into it, I’m not gonna force it.”
