Fans of Kim Kardashian will know the reality star has been trying to conceive again with her husband Kanye West.

Kim and Kanye are hoping that their daughter North will have a little brother or sister soon, but the journey has not been as smooth as they had hoped.

Just last week, a preview clip from Keeping Up With the Kardashians revealed that if Kim does give birth again, doctors may be forced to carry out emergency surgery to remove her uterus immediately after the baby is born, and now the mum of one has received some more upsetting news.

In last night's episode of KUWTK, Kim made the decision to undergo a surgical procedure to improve her chances of conceiving, which involved removing parts of the placenta still attached to her uterus since North's birth.

However the 33-year-old was left devastated when a doctor told her that she may still need to consider surrogacy for her second pregnancy.

"You can still get pregnant but it does expose you to risks during the pregnancy. Surrogacy is the only way to give you a nice, healthy pregnancy and a nice healthy baby," said the fertility doctor.

Having hoped to conceive naturally, Kim was visibly upset by the news, saying it was her "last resort."

The mum of one said the idea of surrogacy terrified her. "Surrogacy is really scary for me, I don’t want one. I don’t want that to be my reality," she said.

"I wouldn’t dare ask anyone to do this for me. It freaks me out. What if they’re a lunatic, what if they run off with my baby? I can’t do it, I just can’t.”

Kim also opened up about the stress of trying to conceive naturally again. "Trying for baby number two is not fun like baby number one. I'm like ‘'I'm ovulating in five minutes, get over here," she admitted.

We hope things work out for her and Kanye.
