View StoryKim previously made it clear on the family's reality TV series, "Keeping Up With the Kardashians," that she wanted to expand her family but wasn't able to do so since she suffered from placenta accreta during her last pregnancy.
"My doctor had to stick his entire arm in me and detach the placenta with his hand, scraping it away from my uterus with his fingernails. How disgusting and painful," she wrote on her blog. "My mom was crying she had never seen anything like this before. My delivery was fairly easy, but then going through that -- it was the most painful experience of my life. They gave me a second epidural, but we were racing against time, so I just had to deal."
