Kim Kardashian says she complained a lot during her pregnancy with North West, but now she’d give anything to be able to conceive.

The reality star said on a recent episode of Keeping Up With The Kardashians that she might be unable to have more children, something she’s known was a possibility for a while. Because her placenta reportedly grew into her uterus, Kim says if she wants more kids she might have to take her doctor’s advice and find a surrogate.

“I complained so much about how I hated being pregnant, and I never thought I would be begging to be pregnant,” Kim said.

Kim and husband Kanye West said last year that they were trying to get pregnant, and Kim was reportedly spotted at a doctor’s office just before Christmas, but there’s been no pregnancy news yet. Kim said she was extremely lucky to get pregnant the first time.

“It’s kind of a miracle that I even got pregnant. Khloé has been very open about her fertility issues and I think I was always really kind of quiet about mine, and I have similar issues,” Kim said on the Today show.

Kardashian told Elle UK earlier this year that she has been told in the past that she would never be able to have children.

“A few years ago I was told I could never get pregnant. Three different doctors told me the same thing, which is why I wanted to have my eggs frozen. I was just about to do that when I found out I was pregnant with North,” she said.

In the same recent episode of Keeping Up With The Kardashians, Kim had a long talk with mom Kris Jenner about her brother Rob, who is reportedly battling depression and has kept himself isolated from the rest of the family. Rob, meanwhile, is rumored to be working on a tell-all book about the famous family.
