Khloe Kardashian-Odom and her husband Lamar Odom have had trouble getting pregnant since they got married in 2012, and Kardashian will open up about her struggles in the March 31 episode of Kourtney & Kim Take Miami.

Kardashian-Odom tells her sister Kourtney, step-brother Brandon Jenner and his wife Leah Felder in the episode that she and her Loa Angeles Lakers husband have been trying to get pregnant since they got married, according to Us Weekly.

She and Odom married in 2012 after dating for about one month. Kardashian-Odom says on the episode, "About a year ago, we were like, 'Let's just see what happens.' And then when it didn't happen, Kim was like, 'Let's go to the doctor."

Kardashian-Odom said, "I found out I don't ovulate, and now my uterus lining isn't thick enough and I have to take pills to make my uterus lining thicker. If that doesn't get thicker, then I cannot carry a baby."

Kourtney Kardashian says in a confessional, "It just makes me sad that she has to struggle with getting pregnant."

Kourtney Kardashian talked with her boyfriend and father of their two babies, Scott Disick, about being a surrogate for her sister. He didn't agree with the idea at first, but then says, "I still think it's a huge decision but I understand how you'd want to do that for your family."

When Kourtney asks Khloe about the idea, Kardashian-Odom says, "I think it is very sweet that Kourtney offers t have my baby in her small uterus."
