KardashiansKhloe Kardashian is ready to start a family with hubby Lamar Odom.

"I thought I'd be pregnant by now," she tells Life & Style. "We've been working at it all year."

She isn't phased, however. "Getting pregnant is much harder than we thought - but practicing making babies is amazing!"

A source close to the family even adds that the Los Angeles Laker bought a fertility monitor for his wife.

"Khloe's been using the monitor for about a month now. They're trying more actively than ever before. Lamar is very serious - Khloe should be pregnant very, very soon," the insider explains.
