Pregnant Kim Kardashian PULLED OVER -- Your Darkness Is a Problem

Kim Kardashian likes her windows like she likes her men ... the darker the better ... but moments ago, her tinted windows got her in trouble with the cops ... TMZ has learned.

KK was pulled over in Calabasas earlier today while on her way to the Kardashian family compound.

But this story has a happy ending for Kim -- we're told the cops only gave her a warning ... NO TICKET.

Kanye West had similar luck in January, when cops pulled over Kanye for speeding and tinted windows ... but let him go with a warning.
