The 34-year-old mom has opened up about her and husband Kanye West's desire to have a second child, and admitted getting pregnant with 1-year-old North was much easier than their tries for another baby.
"When you're not planning it, it happens. It's just how God works," the reality star told the UK's Daily Mail.
Now that she and Kanye, 37, are actively trying for another child, Kim said their efforts have been in vain so far.
"When you want it so bad, it's not happening," she said.
Kim's fertility struggles will be shown on the upcoming tenth season of "Keeping Up with the Kardashians," in an effort to encourage other women who are experiencing similar challenges.
Season 10 will premiere on E! this spring
