Kim Kardashian: Pregnancy is an adjustment

Kim Kardashian doesn't know why people say "pregnancy is so easy and fun."

She tells People.com "it's definitely an adjustment."

She hasn't had as much of adjustment as Kate Middleton, though, who has suffered from severe morning sickness.

Kardashian says she hasn't been nauseous at all.

As for whether she'll find out the sex of the baby, Kardashian says she will because she doesn't want any surprises.
