"Maybe it's the swelling, the backaches or just the complete mindf--- of how your body expands and nothing fits," she added. "I just always feel like I'm not in my own skin. It's hard to explain.

The reality star, 34, then went on to describe some of the absolute worst parts of carrying a child.
"Do you know you basically have to wear a diaper for two months afterwards?! LOL! No one told me that! #SoSexy," she added. "But I will say, as much as I really hate the whole feeling of being pregnant, I enjoy the challenge of getting my body back after it's all over. I feel so accomplished when I'm back to where I want to be ... So for all my complaining, it's 100 percent worth it and more!!!"
