It's been a long road to baby #3!

Kim Kardashian opened up about her fertility struggles and her decision to have a surrogate carry her third child on last night's episode of Keeping Up with the Kardashians, and she even revealed that she experienced a failed embryo transfer before going the surrogacy route.

"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. 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. But I think everything happens for a reason, because the surrogate that I really loved got approved and she is such a nice person, like she’s so easy to talk to and she’s the perfect fit for us, but we have to decide quickly, are we really going to go through with this or are we gonna wait until we feel more prepared," she explained as she contemplated going forward with their plans to expand their family.

She ultimately decided to, and was visibly anxious as she waited to see if the implantation took.

"This is the craziest waiting game. It’s so frustrating. 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," she told Khloe.

"Before Kimberly got pregnant with Saint, she had an embryo implanted into her and that embryo did not take. So Kim is super nervous and anxious during this waiting period. Of course she wants to know is she or is she not having another baby," Khloe said during the confessional.

So how does she feel about another woman carrying her kid?

"It is frustrating to not be able to do it on your own. It is a weird dynamic. Like I go to all the doctors’ appointments and I try to be really present, but when you’re not carrying it yourself, it is such a fine balance of how much you’re going to be in their lives. I’m seriously so grateful for that and that someone is so selfless and kind to do this, and I definitely want to keep it private. I don’t want people to find my surrogate. Like I don’t want them to harass her. She doesn’t know how to handle stuff like that. This isn’t her world," she admitted.

In the end it was all worth it!
