Oh for God's sake! Less than 2 pages after fearing for her safety because she's pregnant, Ana suddenly changes her mind (p. 413):

"…Perhaps I shouldn't tell Christian. Perhaps I…perhaps I should end this. I halt my thoughts on that dark path, alarmed at the direction they're taking. Instinctively my hand sweeps down to rest protectively over my belly. No. My little Blip. Tears spring to my eyes. What am I going to do?"

Well, because this is a romance about a fertile, heterosexual couple, they will be brainwashed by Baby Magic into abandoning their previous agreement to postpone kids. The Miracle of Reproduction will overawe them, activating their dormant, but hereditary and totally natural, parental instincts. With surprising ease and no ambivalence at all, they will quickly convert to anticipation and adoration of their little Blip. Baby Magic is overtaking Ana even in this paragraph: Automatically characterizing her thoughts of abortion as a "dark path," she "instinctively," without any thought at all, develops protective inclinations. YAY BABEEZ!

I detest this trope so very much. I've discussed before, in relation to Bones' pregnancy on her eponymous show, the trivializing, insulting and misogynist ways pregnancy is portrayed in popular media. It compresses a range of emotional, intellectual and characterological responses into a single trajectory of blissfully complaisant, essentialized and instinctive [ergo brainless] femininity. It's pretty much always a horrible derailment of character that represents a descent into utter boredom.

This can't end well either.
