'KUWTK:' Kim Gets TMI about trying to get pregnant again

Kim Kardashian West is serious about giving her daughter North a sibling. And we mean serious.

"The doctor said when I have sex, I have to lay down for, like, 10 to 20 minutes, so I just had sex before you guys got here," said Kim Kardashian on "Keeping Up with the Kardashians."

"Was Kanye just here? I thought I saw him," said Khloe Kardashian.

"Yeah. I was like, 'I'm ovulating today,' so I made him come to my photo shoot," said Kim.

"You didn't bone in a bathroom," said Khloe.

Talk about TMI! Kim revealed during Sunday's premiere of "Keeping Up with the Kardashians" she and husband Kanye West have been trying to get pregnant "500 times a day." Because that's totally possible.

In fact, Kim spent most of the episode obsessively tracking her ovulation cycle, sneaking quickies in with Kanye during photo shoots and even visiting a fertility doctor.

Hey, at least no one can say Kim isn't trying her hardest. Though we're guessing Kim's family wishes she would stop being so vocal about it.

But we're sure the Kardashian Klan will be thrilled once Kim and Kanye welcome another bundle of joy into the world.

The proud mom told People late last year she can't wait to have a second child around the house. "We've really been trying for another kid. More kids can't come soon enough!"

Well, maybe she can get a few pointers from her stepbrother, Brandon Jenner. He and his wife Leah announced Sunday they're expecting their first child together.

We wish you the best of luck, Kim! To see more of the reality queen, you can check out brand-new episodes of "Keeping Up with the Kardashians" Sundays on E!
