Could North West be getting a sibling?

Kim Kardashian and Kanye West just returned from their ski vacation in Deer Valley this morning, and the couple went straight from the airport to the doctor's office in Beverly Hills. All signs point to the reality star being pregnant again, or at least trying to be!

A source tells X17:
    "Kim was totally on edge as she and Kanye went to the doctor's office. She was in no mood for the cameras and seemed really nervous."

The brunette beauty recently opened up about her trouble conceiving another child, and her struggle will be featured as a storyline on the new season of Keeping Up with the Kardashians.

"It's been more challenging to get pregnant the second time around. 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," she told reporters at E!'s International press event for the show.

Kimmy K better be ready to part with her hot bod if she has another little one on the way!
