No. She was certainly considering it - she didn't quit smoking and literally the last word we ever heard from her on the subject was "who said I'm keeping it" (and there's no sign of a kid in the flashforward issues, not that that means *anything* whatsoever). But the way she talks about Dylan and how badly she needs to find him in that scene, especially the way she talks about the pregnancy, suggests that if she did have Dylan around, she'd consider her options differently, so if he showed back up at some point between then and now she might have reconsidered. Anyway, either way she never actually got one that we saw. It would be fairly standard modern comic, frankly, to have her miscarry as a result of just this sort of event-related shenanigan right when she'd finally decided to keep the kid after all, or whatever.
