Kim Kardashian on the difficulty of using a surrogate

Kim Kardashian finally divulged details about her surrogate situation in the latest episode of “Keeping Up with the Kardashians.”

“Getting a surrogate and finding someone that you really trust really is so much more for difficult of a situation than you could really imagine,” Kim, 37, shared, according to People. “You have to like make sure that their lifestyle is healthy and they have to go through psychological testing, and it was maybe a year before we finalized our current situation.”

Kim adds the chosen surrogate for her and husband Kanye West is a “nice person” but wants to protect her identity.

Elsewhere in the episode, Kim confessed that using embryos to get pregnant isn’t a surefire deal and recalled losing an embryo.

“It’s so frustrating,” she said. “It’s really nerve-wracking because you know it’s only a 60 percent chance it’ll take. One didn’t work for me. I tried it and I lost one of them.”

Sister Khloé Kardashian explained it a bit further saying before Kim got pregnant with son Saint, an embryo was planted but it didn’t take. “So Kim is super nervous and anxious during this waiting period,” she said.

Kim and Kanye are expecting a daughter via surrogate very soon, but not being pregnant herself has left Kim feeling a bit off.

“It’s kind of weird when it’s not you, so I don’t know whether I should start eating donuts and celebrate like I would like old times or just go to the gym,” she said. “I’m totally gonna forget and then a month before I’m gonna be like holy s–t, we need to get a nursery.”
