Khloe Kardashian's Pregnancy Struggles: 'I Never Knew All The Difficulties' In Trying To Conceive

Much attention has been paid to Kourtney Kardashian and Scott Disick's little bundle of joy, Penelope Scotland. But as we learned on Sunday's episode of "Keeping Up With the Kardashians," Khloe Kardashian and husband Lamar Odom are looking to expand their family too.

Khloe opened up about trying to conceive a child when she and sisters Kourtney, 33, and Kim, 31, appeared on "Good Morning America" Thursday to celebrate the anniversary of their Kardashian Kollection fashion line.

"I never knew all the difficulties with getting pregnant," Khloe, 28, revealed on "GMA." "I think that my mom has so many kids, and Kourtney pops them out like a PEZ dispenser, so you think it's, like, so easy. You realize it's not as easy as you might think."

Kardashian matriarch Kris Jenner, of course, is the mother of six, while Kourtney is mom to 2-year-old Mason in addition to baby Penelope.

"It was really hard for me to show what I was going through," Khloe continued. "I feel like I'm helping a lot of people, but I'm still figuring it out for myself."

Host Lara Spencer asked Kim whether accompanying Khloe on a recent visit to a fertility clinic made her want to "take action" when it comes to having children of her own. "It was really informative to go with Khloe," Kim replied. "I don't think I'm ready yet."

Kim is presumably getting used to fielding such questions about her future with beau Kanye West. Just last week, during an appearance on "The View," Barbara Walters grilled Kim about Kanye, asking, "Do you want his child?"

But for now, Kim is content providing moral support to Khloe.

"I do appreciate Kim pushing me to do that, because I was kind of like, 'I just don't want to know,'" Khloe said. "You do have to know. Kim made a good point: 'You can't run from your problem.' So it's better to know what's going on."
