During part 2 of theKeeping Up with the Kardashiansreunion special Sunday, Khloé, 36, opened up to hostAndy Cohenabout wanting more children with boyfriend Tristan Thompson and the latest developments in securing a surrogate to welcome a second child.

“It’s a very tedious, hard process. And it was interesting because Kim went through the journey, and I swear it felt like she said, ‘I want to get pregnant,’ and two weeks later she found a surrogate,” said Khloé, comparing her experience to sisterKim Kardashian, who welcomed her two youngest kids via surrogate.

“It’s a lot to do with COVID,” Khloé added of her own difficulty with the process during the pandemic. “I did have one and then it fell through. There’s so many tests they have to do and all these things. So I’m still on that journey. It’s just, I thought it would be a much easier process. And it’s not. It’schallenging for me.”

Khloé also spoke about regaining trust in Thompson, with whom she shares 3-year-old daughter True, after a past cheating scandal.

“I know the growth and all the work that he’s done, I know all of the help that he’s gotten and the constant efforts that he makes every single day and how hard he fought to get back with me currently,” she explained. “I mean, you can ask everyone, it really wasn’t an easy thing for him. I don’t understand why someone would go through all that if they weren’t serious.”

The Good American co-founder and the NBA player, 30, have been going strong sincegetting back togetherlast summer after self-isolating with True during the pandemic.

“In the past few months, Tristan has really shown Khloé that he has changed,” a source previouslytold PEOPLE. “He is an amazing dad and partner.”

On Twitter in May, Khloé noted that everyone’s experience is different, especially since Kim had two positive experiences with surrogacy: “Watching my sister go through her surrogacy journey it seemed so seamless and easy. maybe it is for some people. My journey has been a lot more intense and grueling but still a huge blessing.”

“My own sister went through the surrogacy journey and I thought I knew so much about it,” she added inanother tweetat the time. “I realized I was very naïve to the process until I embarked on my own journey. Every journey is different.”
