The reality TV star battled a number of health issues during her first pregnancy and required surgery on her uterus after giving birth to North in 2013, but, although the experience initially turned her off the idea of having a second child, she later decided the pain would be worth it to give her little girl a sibling.

However, falling pregnant a second time proved to be a lot harder than expected, and Kardashian documented her struggles to conceive and her subsequent fertility treatment on her show Keeping Up With the Kardashians.

Kardashian and West are now expecting a baby boy, and the TV beauty admits she has already started to think about expanding their family once more.

She tells U.S. breakfast show Today, "We might try for another one, if, God willing, that works out for me. Maybe. Let's see how the rest of it (pregnancy) goes, but never say never."

Kardashian also used the interview to dismiss "false" reports suggesting she only had male embryos implanted during in vitro fertilisation (IVF) treatment - to make sure her second child would be a boy, stating, "I'm grateful to just be pregnant. We'd be happy with a boy or girl."

And she adds of her growing figure: "I've gained, like, 15 pounds already, almost. It's gone everywhere. It's in my boobs right now; my boobs are huge!

Kardashian is due to give birth at the end of the year (15).
