The Keeping Up With The Kardashians star has made no secret of the fact she and husband Kanye West want to add to their family but says it won't be happening just yet.
"We have been trying. I am not pregnant, not that I know of! I wish I was. I'm about 15lbs heavier but I'm not pregnant," she told Entertainment Tonight.
Kim and Kanye are already parents to daughter North, who turns two in June.
The 34-year-old admitted earlier this month that she was finding it more difficult to fall pregnant for a second time, saying: "When you're not planning it, it happens. It's just how God works. And when you want it so bad, it's not happening..."
The star's difficult pregnancy with North back in 2012-3 was well documented, with her describing it as "medically tough and challenging" but worth it in the end.
She's said openly she would love to have three or four children if possible as she grew up as part of six children and loved the experience.
Kim's sister Kourtney gave birth to a baby boy, Reign Aston, in December.
