We've been worried about Meredith's (Ellen Pompeo) baby ever since we saw the preview for Grey's Anatomy Season 9, Episode 13: "Bad Blood," and now, thanks to a new sneak peek from Entertainment Weekly, we're more concerned than ever.

In the clip of the episode, which you can see here, Mer starts to freak out while hard at work, telling Bailey (Chandra Wilson) that "something's wrong." She feels a "flutter" that "can't be right."

Does she really have a problem, or is it all in her head?
